12 Best Men’s Underwear In Australia (2026 Buyer’s Guide)*

Your underwear shouldn’t be something you think about after you put it on. Yet here you are, adjusting, shifting, and dealing with the same problems every bloke knows too well: chafing between the thighs, fabric that bunches in all the wrong places, support that’s either non-existent or uncomfortably tight, and that swampy feeling by midday. The underwear drawer is probably full of different brands you’ve tried, each one promising comfort but delivering disappointment. Whether you’re sitting at a desk, working on site, hitting the gym, or just going about your day, rubbish underwear can turn any activity into an endurance test.

This guide cuts through the noise and ranks twelve of the best men’s underwear options you can buy in Australia right now. We’ve evaluated each pair on fabric quality, support features, comfort, durability, sizing, and value for money. From bamboo pouch innovations that actually eliminate chafe to reliable everyday basics that won’t let you down, every brand here earned its spot through real-world testing and honest assessment. You’ll find detailed breakdowns of what makes each option worth considering, who they’re best suited for, and where the trade-offs lie.

1. SLY Collective bamboo pouch boxer briefs

SLY Collective claims the top spot among the best men’s underwear australia 2025 has to offer, and the reason comes down to solving the exact problems you’re dealing with. These bamboo boxer briefs feature a patented three-panel pouch that physically separates your skin from touching itself, eliminating chafe at the source rather than just managing it. The design doesn’t rely on powder, special fabrics, or wishful thinking. It works through mechanical separation.

“Australian manufacturing means your dollars stay local while getting underwear built to last.”

Why this underwear made the list

The built-in pouch delivers what other brands only promise. Thigh chafing stops completely because the pouch lifts everything away from your legs, and the longer leg design prevents ride-up that causes fabric to bunch. You also get a genuine pocket built into the waistband, useful for stashing cards, keys, or cash when you’re travelling or don’t want to carry a wallet.

Temperature regulation matters for testicular health, and bamboo naturally stays cooler than cotton.

If you want to explore our range, why don’t you take 20% off your first order – use SLY20 at the checkout. Remember you have a ‘first pair guarantee’ as well, so you’ve got nothing to lose.

Fabric and construction

The bamboo viscose blend provides genuine temperature control, staying two to three degrees cooler than standard cotton while wicking moisture effectively. Construction quality sits well above budget brands, with flat-lock seams that don’t irritate and reinforced stitching at stress points. The fabric holds its shape through repeated washing without that saggy, worn-out feeling cheap underwear develops.

Support and comfort features

Support comes from the anatomical pouch structure rather than compression, so you’re not being squeezed into position. The waistband stays put without rolling or digging, and the 18cm inseam gives coverage without excess fabric. Comfort remains consistent whether you’re sitting for hours or moving constantly.

If you want to explore our range, why don’t you take 20% off your first order – use SLY20 at the checkout. Remember you have a ‘first pair guarantee’ as well, so you’ve got nothing to lose.

Best for

These excel for blokes who’ve tried everything else and still deal with chafing between the thighs, anyone working long shifts on their feet, and active guys who need underwear that performs during exercise without adjustment. The pocket feature makes them particularly useful for travellers and minimalists.

Potential drawbacks

The pouch looks snug in the packet, which can be off-putting until you wear them. Price per pair runs higher than supermarket multipacks, though the durability and chafe elimination justify the cost for most buyers. Some blokes initially find the pouch unusual if they’re used to traditional flat-front designs.

Sizing and fit

Sizing runs true to Australian standards from S to XXXL. Measure around your hips at the widest point and match the size chart. The pouch accommodation is generous, so you don’t need to size up for that reason.

Price and value in Australia

Individual pairs cost more than budget options, but free shipping applies to orders over $100, and a 30-day comfort guarantee removes purchase risk. The longevity of these boxer briefs means you’ll replace them less frequently than cheaper alternatives.

2. Step One bamboo anti chafe trunks

Step One built their reputation on social media videos showing blokes testing their chafe prevention claims during runs, and the product delivers what the marketing promises. These bamboo trunks sit firmly in the conversation about Australia’s best men’s underwear for good reason: they combine FSC-certified bamboo fabric with strategically placed panels that genuinely stop friction.

Why this underwear made the list

The Ultra-Glyde panels run down the inner thigh area, creating a barrier between fabric and skin that prevents the rubbing which causes chafe. Step One also holds Ethical Clothing Australia accreditation and ships in compostable packaging, appealing to buyers who consider environmental impact alongside comfort.

Fabric and construction

Bamboo viscose forms the base material, offering natural moisture-wicking and temperature regulation similar to SLY Collective’s fabric. Construction quality remains consistent across their range, with vegan certification and flat seams that don’t create pressure points.

Support and comfort features

Support comes from a contoured front panel rather than a full pouch design, providing lift without the separation structure. The shorter leg length compared to SLY suits blokes who prefer less coverage, and the fabric breathability handles Australian summer conditions effectively.

Best for

These work particularly well for runners and gym-goers who need reliable chafe prevention during high-movement activities. The shorter trunk style appeals to blokes who find longer legs restrictive or visible under slim-fitting trousers.

Potential drawbacks

The contoured panel provides less separation than dedicated pouch designs, meaning you might still experience some skin-on-skin contact in extreme humidity. Loud branding on some styles doesn’t suit blokes wanting minimal logos.

Sizing and fit

Sizing covers XS to 5XL, running true to standard Australian measurements. The trunk cut sits lower on the leg than boxer briefs, so check the inseam length before ordering if coverage matters to you.

Price and value in Australia

Individual pairs fall in the $25 to $35 range, with bundle packs reducing the per-pair cost below $20. A 30-day return window lets you test them properly before committing.

3. Boody everyday bamboo trunks and briefs

Boody proves that sustainable basics don’t require sacrificing comfort or breaking the budget. This Sydney brand holds B-Corp certification and builds its men’s underwear line around pure bamboo fabric that handles Australian conditions without fuss or flashy features.

Why this underwear made the list

These trunks and briefs deliver consistent everyday comfort through hypoallergenic fabric that suits sensitive skin particularly well. The OEKO-TEX certification guarantees freedom from harmful chemicals, and the closed-loop production system recycles water and solvents rather than dumping them. You’re getting solid environmental credentials alongside functional underwear.

Fabric and construction

The 95% bamboo viscose blend with minimal elastane creates a lightweight, breathable fabric that regulates temperature naturally. Boody uses FSC-certified bamboo grown without irrigation, and construction features completely side-seam-free design that eliminates common irritation points.

Support and comfort features

Support remains basic compared to pouch-equipped options, relying on a contoured front panel for modest lift. The tag-free waistband and flat seams prevent chafing at contact points, while the fabric’s natural properties resist odour buildup through long days.

Best for

These suit blokes wanting simple, sustainable basics without complex features or loud branding. The hypoallergenic properties benefit anyone with skin sensitivity or eczema, and the minimalist aesthetic appeals to buyers seeking understated everyday wear.

Potential drawbacks

Basic support means you won’t get the separation or lift that dedicated pouch designs provide. The S to XL size range excludes larger blokes who need extended sizing options.

Sizing and fit

Sizing follows standard jeans waist measurements, making ordering straightforward. The trunk offers an 8cm inseam while the boxer brief provides longer leg coverage for ride-up prevention.

Price and value in Australia

Boody positions itself as affordable eco-friendly basics, with pricing below premium bamboo brands while maintaining ethical production standards. Durability matches the modest price point rather than exceeding it.

4. Bonds GuyFront and Move trunks

Bonds represents Australian underwear heritage going back to 1915, and the brand still dominates supermarket aisles and department stores across the country. The GuyFront and Move trunks earn their place in this guide through sheer accessibility, reliable quality, and pricing that lets you stock your drawer without financial stress. While you won’t find cutting-edge pouch technology or bamboo fabrics here, you will find solid everyday underwear that does the job without fuss.

Why this underwear made the list

These made the list because availability matters when you need fresh underwear quickly, and Bonds sits on shelves everywhere from Woolworths to Target. The 4-way stretch cotton in the GuyFront range provides familiar comfort that most Australian blokes grew up wearing, while the newer Move line adds moisture-wicking microfibre for active days.

Fabric and construction

The GuyFront trunk uses traditional cotton-elastane blend with enough stretch to move comfortably without losing shape. Construction quality remains consistent across their massive production runs, with soft waistbands that don’t dig and reinforced stitching at stress points. The Move range switches to synthetic microfibre that handles sweat better than straight cotton.

Support and comfort features

Support comes from traditional flat-front design rather than pouches or contoured panels, providing basic coverage without specialized lift or separation. The soft waistband prevents rolling, and the trunk cut offers moderate leg coverage that works under most trousers without visible lines.

Best for

Bonds suits budget-conscious buyers needing to replace multiple pairs at once, teenagers starting their first proper underwear drawer, and blokes wanting reliable basics they can grab anywhere without ordering online.

Potential drawbacks

The flat front provides minimal anatomical support compared to pouch designs, and colour options tend conservative rather than bold. Performance seekers looking for advanced features will find Bonds basic.

Sizing and fit

Sizing runs XS to XXXL following standard Australian measurements, making them accessible for most body types. The trunk cut sits comfortably without riding up excessively.

Price and value in Australia

Multi-pack pricing makes these among the cheapest per-pair options in this guide, with frequent sales pushing prices lower. You’ll find them at every major retailer, so comparing prices takes seconds.

5. aussieBum bold briefs and trunks

aussieBum brings Bondi beach confidence straight to your underwear drawer with designs that refuse to blend into the background. Founded in 2001 by Sean Ashby, this brand keeps production entirely on Australian soil, supporting local manufacturing while delivering underwear that combines practical comfort with eye-catching style. You’ll find everything from classic cotton trunks to metallic party briefs in their range.

Why this underwear made the list

These earned their spot through genuine Australian manufacturing and the Wonderjock pouch technology that provides lift without padding or inserts. The brand champions body confidence through designs that actually enhance rather than hide, and recycled ocean nylon in their EcoPower line proves sustainability doesn’t require sacrificing style.

Fabric and construction

The CottonSoft series delivers breathable everyday comfort through traditional cotton blends, while the EcoPower range transforms ocean waste into performance nylon. Construction quality reflects local manufacturing standards, with attention to seam placement and waistband finishing that cheaper imports skip.

Support and comfort features

Wonderjock pouch technology creates natural lift and definition through strategic panel placement rather than foam or gel inserts. The lower hip cut sits differently than traditional briefs, appealing to blokes who want contemporary styling alongside functional support.

Best for

These suit confident blokes wanting underwear that makes a statement, anyone prioritising Australian-made goods, and buyers seeking bold colour options beyond basic black and grey.

Potential drawbacks

The lower hip cut runs smaller than supermarket standards, so ordering up prevents waistband squeeze. Limited sizing compared to inclusive brands, and bold styling doesn’t suit conservative preferences.

Sizing and fit

Most designs ride lower on the hips than traditional briefs, requiring you to check measurements carefully. 90-day returns give plenty of time for swapping sizes.

Price and value in Australia

Pricing reflects local manufacturing costs, sitting above imported brands but delivering Australian jobs and quality control alongside your underwear.

6. 2EROS CURV performance underwear

Melbourne-born 2EROS blends athletic performance with fashion-forward styling that transitions seamlessly from gym to beach to street. Founder Jason Hoeung designed the patented CURV pouch to lift away from your thighs while maximising ventilation, creating underwear that performs under pressure and looks sharp doing it. The brand targets blokes who refuse to compromise between function and aesthetics.

Why this underwear made the list

The CURV pouch technology delivers genuine anatomical support through ergonomic shaping rather than basic fabric panels. Quick-dry microfibres and bamboo blends handle Australian heat effectively, while bold colourways satisfy buyers wanting personality in their underwear drawer. The 2025 Aether range adds removable pouch inserts for customisable support levels.

Fabric and construction

Lenzing Modal in the premium Adonis collection provides silky texture and moisture management, while the V10 sportive line uses quick-dry microfibre with four-way stretch. Construction features flat-lock seams and gold trim details on select styles that elevate these beyond basic athletic underwear.

Support and comfort features

The CURV insert lifts and separates your anatomy from your thighs, preventing the skin-on-skin contact that causes chafe. Low-rise cuts suit modern trouser styles, and breathable mesh panels boost airflow during intense activity.

Best for

These excel for gym enthusiasts wanting underwear that performs during workouts and looks good in change rooms, plus style-conscious buyers seeking eye-catching designs that stand out from conservative basics.

Potential drawbacks

Cuts run deliberately snug and low, requiring you to size up if you prefer relaxed waistbands. Premium styling commands premium pricing compared to everyday basics.

Sizing and fit

Check measurements carefully as 2EROS fits closer than standard Australian brands. Sizing up prevents waistband restriction without compromising support.

Price and value in Australia

Individual pairs cost more than budget options, but loyalty points accumulate quickly and orders over $120 ship free across Australia.

7. Debriefs micromodal second skin trunks

Brisbane-based Debriefs proves you don’t need flashy prints to stand out among Australia’s underwear brands. Instead, the company perfected feel-like-skin basics and backed them with a lifetime warranty that covers holes and defects. Their direct-to-consumer model cuts retail margins, channelling savings into premium MicroModal fabric that creates what testers consistently describe as the softest underwear they’ve worn.

Why this underwear made the list

These trunks earned their spot through genuine comfort innovation rather than marketing hype. The 3-D jacquard waistband never rolls or digs, and the “No Holes” lifetime guarantee removes purchase anxiety completely. Selling exclusively through their website keeps prices reasonable while maintaining fabric quality that rivals brands charging twice as much.

Fabric and construction

Premium MicroModal forms the base material, delivering silky texture that regular cotton can’t match. The fabric drapes smoothly against your skin without clinging uncomfortably, and hidden stitch work eliminates visible seam lines that create pressure points during long wear.

Support and comfort features

Support comes from anatomical front panels that provide modest lift without pouch separation. The fabric’s natural drape means you won’t experience the restrictive squeeze some underwear creates, and moisture management keeps you dry through Australian summer conditions.

Best for

These suit minimalist buyers wanting understated everyday comfort, anyone allergic to logos and loud patterns, and blokes seeking premium fabric quality at mid-range pricing.

Potential drawbacks

The basic support structure won’t satisfy buyers needing dedicated pouch designs for maximum separation. Limited colour options focus on neutral earth tones rather than bold statements.

Sizing and fit

Sizing runs true to Australian standards, following standard waist measurements for straightforward ordering. The trunk cut provides moderate leg coverage without excess fabric.

Price and value in Australia

Singles cost $28, dropping to approximately $20 when you subscribe for six-month automatic refreshes. Free shipping applies to orders over $60 Australia-wide.

8. Knobby subscription printed trunks

Queensland-born Knobby turns the underwear shopping experience on its head through a monthly subscription model that delivers surprise prints straight to your door. The brand commits a slice of every drop to emerging illustrators and grassroots charities, meaning your undies fund creative talent and community causes while keeping your drawer fresh with designs you won’t find anywhere else.

Why this underwear made the list

The subscription model eliminates decision fatigue while ensuring you constantly rotate through bold, artist-designed prints that sell out before hitting stores. Free signup means zero lock-in contracts, and the app lets you skip, swap, or cancel whenever you want without penalty.

Fabric and construction

Recycled polyester blended with elastane creates vivid, fade-resistant prints that maintain their colour intensity through repeated washing. Flat seams prevent irritation, and the breathable mesh pouch boosts airflow during active days.

Support and comfort features

The mesh pouch provides basic separation and ventilation without the complex structure of dedicated anatomical designs. Mid-rise trunks with a comfort waistband sit securely without rolling or digging.

Best for

These suit blokes craving bold prints and effortless gifting options, plus anyone wanting their underwear purchases to support Australian artists and charities.

Potential drawbacks

The mesh panel offers less separation than full pouch designs, potentially allowing some skin contact in extreme humidity. Print preferences vary, and you can’t preview designs before they arrive.

Sizing and fit

The trunk cut provides moderate leg coverage with a mid-rise waistband that suits most body types comfortably.

Price and value in Australia

$29 monthly delivers exclusive prints unavailable elsewhere, with the added benefit of supporting creative communities through each purchase.

9. Tradie worksite cotton and bamboo trunks

Tradie wears its blue-collar heart on its waistband, building underwear for blokes who’d rather spend money on tools than trunks. The brand trades on tongue-in-cheek TV spots and “Get ’em on ya!” slogans, but the mission stays serious: value gear that survives a 10-hour shift without falling apart or causing discomfort. You’ll find these in Big W, Bunnings, and servo aisles across Australia, making them the most accessible option when you need fresh underwear immediately.

Why this underwear made the list

These made the cut because worksite availability matters when your current pair gives up mid-shift. The roomy cut accommodates tool belts without waistband roll, and thick elastic handles the constant movement that warehouse work, construction, and trades demand daily.

Fabric and construction

Cotton-stretch trunks provide familiar everyday comfort through traditional blends that breathe well in Australian conditions. The newer bamboo options suit sticky climates where sweat becomes problematic, while TradieTech adds moisture-pulling synthetic yarns that keep you dry during physical labour.

Support and comfort features

Support relies on traditional flat-front design cut generously to prevent restriction under work clothing. The reinforced waistband resists rolling when you’re bending, lifting, or wearing heavy belts loaded with gear.

Best for

These suit tradies and labourers needing durable basics that handle sweat and movement, plus budget buyers wanting maximum pairs for minimum spend.

Potential drawbacks

The generous cut might feel loose if you’re used to fitted underwear, and basic support won’t satisfy buyers wanting anatomical pouches.

Sizing and fit

Sizing covers S to XXL following relaxed Australian measurements. The roomy trunk cut prevents restriction during active work.

Price and value in Australia

Multi-packs drop under $15 per pair, with frequent sales pushing prices lower at major retailers nationwide.

10. Bushy Australian made cotton and merino trunks

Melbourne’s Bushy keeps things deliberately simple: small-batch underwear stitched locally from start to finish, then packed in recycled Kraft boxes. The label serves retro surf-shop vibes yet upgrades the build with premium yarns and slow-fashion ethics that reward buyers wanting genuine Australian manufacturing without the marketing fluff.

Why this underwear made the list

These earned their spot through transparent supply chains you can actually trace. Every panel gets cut in Brunswick, sewn in Coburg, and finished with labels from a family-run print house, keeping your dollars circulating through Victorian manufacturing loops rather than disappearing offshore.

Fabric and construction

The classic 130gsm cotton boxer delivers breathable everyday comfort through traditional weaves that last, while the 200gsm superfine merino trunk handles cool-weather layering without bulk. Limited artist collaborations use water-based inks for prints that won’t fade after three washes.

Support and comfort features

Support relies on basic cotton construction without pouches or technical panels. The natural fibres breathe well, and merino options regulate temperature effectively during Melbourne’s unpredictable weather swings.

Best for

These suit buyers prioritising Australian manufacturing, anyone wanting retro aesthetics without sacrificing modern quality standards, and blokes seeking durable basics that justify higher pricing through longevity.

Potential drawbacks

Basic support means you won’t get the anatomical lift that pouch designs provide. Production runs stay deliberately small, so popular styles sell out before restocks arrive.

Sizing and fit

Sizing follows standard Australian measurements across their limited size range. The trunk cut provides moderate coverage suitable for everyday wear.

Price and value in Australia

Pricing reflects local manufacturing costs and small-batch production, sitting above imported alternatives while delivering genuine Australian craftsmanship alongside your underwear.

11. Uniqlo AIRism breathable boxer briefs

Uniqlo’s AIRism range proves you don’t need to spend heavily to get gym-ready performance underwear that handles Australian heat without falling apart. The Japanese retailer designed these boxer briefs for maximum breathability and moisture management, creating surprisingly capable workout companions at a fraction of what dedicated athletic brands charge. You’ll find these in every Uniqlo store across Australia, making restocking straightforward when you need fresh pairs quickly.

Why this underwear made the list

These made the list because $15 delivers genuine athletic performance rather than basic cotton that turns soggy during exercise. The polyester-spandex blend wicks sweat effectively while maintaining enough stretch for full range of motion, and the lightweight feel prevents the bulky sensation that some performance fabrics create.

Fabric and construction

The 89% polyester, 11% spandex blend creates smooth texture against your skin without the rough feel that pure synthetics sometimes produce. Construction quality remains consistent across Uniqlo’s manufacturing, with flat seams that prevent irritation during movement.

Support and comfort features

Support comes from a functional side fly that provides access without compromising the contoured front panel. Moisture-wicking abilities keep you dry through workouts, and the fabric’s natural stretch accommodates movement without restriction.

Best for

These suit budget-conscious buyers wanting performance features without premium pricing, gym-goers needing multiple pairs for frequent training sessions, and active blokes seeking reliable moisture management.

Potential drawbacks

The basic support structure won’t match dedicated pouch designs for anatomical separation. Sizing could be better tailored compared to premium athletic brands.

Sizing and fit

Sizing runs S to 3XL following standard measurements. Check the sizing chart carefully as Uniqlo sometimes cuts slightly smaller than Australian brands.

Price and value in Australia

$15 per pair makes these among the most affordable performance options in this guide, with in-store availability eliminating shipping costs entirely.

12. Calvin Klein cotton stretch boxer briefs

Calvin Klein defined designer underwear in the 1980s and continues delivering reliable basics that balance comfort with brand recognition. These cotton stretch boxer briefs remain a staple across Australian retailers, offering familiar quality that generations of blokes have trusted. You’ll find them everywhere from department stores to online marketplaces, making replacement straightforward when your current pairs wear thin.

Why this underwear made the list

These earned their place in the best men’s underwear australia 2025 rankings through sheer consistency and accessibility. The 5% spandex blend provides stretch without losing shape after repeated washing, and the contoured pouch delivers basic support that suits everyday wear. Brand recognition means you know exactly what you’re getting before opening the packet.

Fabric and construction

The 95% cotton, 5% spandex construction creates soft, breathable fabric that handles Australian conditions without excessive heat retention. Flat seams prevent irritation at contact points, and the waistband resists sagging through extended wear and washing cycles.

Support and comfort features

Support comes from a contoured front pouch that provides lift without separation technology. The functional fly adds convenience, and the fabric’s natural stretch accommodates movement comfortably throughout your day.

Best for

These suit brand-loyal buyers wanting designer credibility without extreme pricing, plus blokes seeking reliable everyday basics they can purchase almost anywhere in Australia.

Logo waistbands aren’t for everyone, but they’ve defined Calvin Klein’s aesthetic for decades.

Potential drawbacks

The prominent branding doesn’t appeal to minimalists wanting subtle underwear. Support levels fall short of dedicated pouch designs.

Sizing and fit

Sizing covers S to XL following standard measurements. The boxer brief cut provides moderate leg coverage that works under most trousers.

Price and value in Australia

Multi-packs frequently drop below $15 per pair during sales, making these among the most affordable designer options available locally.

Final thoughts

Finding the best men’s underwear australia 2025 has to offer comes down to matching your specific needs with the right design features. Chronic chafing demands dedicated pouch technology rather than flat-front basics. Budget constraints point you toward multipacks from reliable brands like Bonds or Tradie. Sustainability priorities lead to bamboo options from SLY Collective, Step One, or Boody. Athletic performance requires moisture-wicking fabrics that handle sweat without turning soggy.

Your underwear drawer shapes how every day feels from the moment you get dressed. Quality pairs eliminate adjusting, shifting, and discomfort that ruins concentration and confidence. While premium options cost more upfront, they outlast cheap multipacks through superior construction and materials that maintain their shape through countless washes.

If thigh chafing has plagued you despite trying different brands, check out SLY Collective’s bamboo pouch boxer briefs that mechanically separate skin contact. The 30-day comfort guarantee removes purchase risk completely.
