Every bloke knows the feeling: that creeping heat, the damp cling, the all-too-familiar chafe that turns a busy day into a slow burn. Whether you’re pounding the pavement, desk-bound under fluorescent lights, or just trying to stay fresh through a sweltering Aussie summer, ordinary underwear can become an uncomfortable liability. That’s where cooling underwear for men steps up—purpose-built to keep your gear dry, cool and supported, no matter what the day throws at you.
Cooling underwear isn’t just about fancy fabric tags. It’s a smart combination of moisture-wicking technology, innovative cuts, mesh panels, and temperature-regulating fibres—all designed with the male anatomy in mind. A quality pair does more than fend off sweat: it keeps you comfortable for longer, reduces the risk of irritation, and can even contribute to better hygiene and testicular health. For the health-conscious or the active, the right design may even help maintain optimal temperature for sperm quality and overall wellbeing.
To separate the true game-changers from the gimmicks, we’ve compared everything from laboratory-certified cooling performance and sustainable materials, to anatomical pouch engineering and real-world durability. Our line-up spotlights the best in the business: from Australian bamboo pioneers and medically approved cooling briefs, to seamless budget-friendly staples and technical mesh options for sport.
If you’re searching for the ultimate sweat-free comfort, you’ll find your next go-to pair below—no matter your style, budget or activity. Let’s get started.
1. SLY Collective Bamboo Cooling Pouch Boxer Briefs
Overview & Unique Design Principles
SLY Collective is an Australian-designed brand inspired by street art and tattoo culture, committed to reinventing men’s underwear from the ground up. Their Bamboo Cooling Pouch Boxer Briefs feature a patented inner pouch that gently separates and supports your anatomy, eliminating skin-on-skin friction and chafing. With a longer leg design, these boxer briefs stay put under shorts or jeans, preventing ride-up and bunching even during the most active days. Discover more at the SLY Collective website.
Cooling & Comfort Features
The secret to these briefs lies in their bamboo fabric. Naturally breathable and moisture-wicking, it draws heat and sweat away from the skin, keeping you feeling fresh rather than drenched. Bamboo fibres also regulate temperature, helping you avoid overheating—and potentially safeguarding sperm health by maintaining a cooler microclimate. Plus, there’s a subtle “nifty pocket” integrated into the pouch, perfect for stashing a key, card or even a spare condom when you’re on the move.
Material, Certification & Sustainability
SLY Collective’s fabric has been tested to ISO 11092:2014 standards for thermal and moisture management, so you can trust its cooling performance is independently verified. Life-cycle assessments from MDPI show that bamboo requires far less water than conventional cotton (cotton’s footprint is around 1,736 m³/ton of water, whereas bamboo’s is significantly lower). On top of reduced irrigation needs, bamboo cultivation typically involves minimal pesticides, lower chemical runoff and natural pest resistance. And once they retire, these boxer briefs biodegrade much more readily than synthetic alternatives.
Fit, Sizing & Practicality
These boxer briefs are available in sizes S–XXL; we recommend choosing your usual underwear size for a snug, supportive fit. For best results, machine-wash on a cool cycle and air-dry to preserve the pouch’s shape and the fabric’s moisture-wicking finish. If you’re between sizes or unsure, SLY Collective offers free size exchanges, so you’ll never be stuck with the wrong fit.
Pricing, Guarantees & Where to Buy
A single pair is priced at AUD 35, with bundle discounts available when you add two or more pairs to your cart. Every purchase is backed by SLY Collective’s Comfort Guarantee—return your first pair for a full refund if they’re not the most comfortable briefs you’ve ever worn. Plus, enjoy free shipping on Australian orders over AUD 100. Grab yours directly from the official SLY Collective store: https://slycollective.com

Snowballs Underwear is built around one mission: keep your nether regions at an optimal temperature for fertility and comfort.

By targeting precise temperature control, Snowballs positions itself at the intersection of everyday underwear and medical-grade cooling wear.
Cooling Technology & Benefits
At the core of Snowballs briefs is the proprietary brrr° cooling fabric, proven to lower scrotal temperature by up to 3 °C in clinical tests. Reduced testicular heat has been linked to improved sperm motility and counts, making these briefs more than just a comfort upgrade—they can actively support reproductive health. Wearers also report relief from scrotal pain and significantly less sweat buildup, thanks to enhanced moisture management and airflow.
Material & Construction
Snowballs uses a cotton-polyester blend treated with a specialised cooling finish to wick moisture away from the skin. A three-dimensional anatomical pouch gently separates and supports your anatomy, reducing friction and chafing during movement. Surrounding the pouch, integrated airflow channels encourage continuous circulation so heat and moisture don’t ever get trapped against the skin.
Sizing, Price & Where to Buy
Available in sizes S–XXL, Snowballs briefs should be chosen by your regular waist measurement—consult the brand’s online size chart for precise guidance. They’re sold in two- or three-pack bundles, with each pair priced around AUD 45–50 when bought in multi-packs.

As part of Under Armour’s flagship Performance Tech™ range, it combines lightweight comfort with strategic ventilation to tackle heat and sweat head-on.
Ventilation Zones & Fast-Drying Fabric

It delivers the familiar fit and feel you expect from Hanes, but with added tech to keep you dry and comfortable through workdays, workouts and weekends alike.
X-Temp™ Technology & Moisture Management
At the core of the Moves brief is Hanes’ X-Temp™ technology—strategically placed cooling zones in the crotch that react to body heat. As you warm up, the fabric opens up to allow air flow and disperses moisture, then closes back down as you cool. This adaptive response pairs with a fast-dry nylon/spandex mix that swiftly pulls sweat away from your skin, so you’ll never deal with that damp-clinging feeling.
Material & Durability
