Yes – underwear with a built-in pocket is a real thing, and it means you can stash a credit card, a house key or even a passport without lugging a bag or bulky wallet. From zipped security compartments to supportive pouches that double as storage, smart designers have turned boxer briefs, trunks and running briefs into miniature lockers.
That extra space is changing the game for travellers worried about pickpockets, runners chasing chafe-free freedom, festival-goers who need hands-free convenience, and anyone who simply hates loose coins jabbing the thigh. Below we compare 15 of the top styles, weighing up pocket placement, size, closure, leg length, performance, sizing so you can choose the pair that suits your life and budget. Let’s get straight to the underwear that carries its own cargo. You may be surprised how much a pocket can upgrade daily comfort.

14. Stashitware Boxer Briefs With Deep Side Conceal Pocket
For anyone who hates carrying a bag but still needs room for more than a single card, Stashitware’s boxer briefs pack serious cargo space. Sewn down the entire outer thigh is a covert nine-inch pocket that swallows items most underwear can’t even contemplate: a full-sized smartphone, a slim wallet, trail mix, or even a 500 ml soft flask on a long dog walk. Because the opening sits high on the hip and the stretchy cotton knit grips firmly, contents stay flat and silent under jeans or boardies.
- Deep vertical pocket: 23 cm (≈9 in) length with elastic-bound mouth; no zip, so nothing digs into skin.
- Capacity: phone, passport, small power bank or festival map—ideal for events where belt pouches are banned.
- Fabric: 95 % ringspun cotton / 5 % spandex delivers familiar softness with enough give to prevent sag when loaded.
- Cut: 7 in inseam, mid-rise waist and flatlock seams for chafe control.
Who it suits: campers, festival-goers, commuters, and weekend walkers who want hands-free freedom. Use it for legal valuables only—Stashitware markets the pocket for safety and convenience, not for sneaking contraband past security. Singles run about AUD $42 in sizes S–3XL, with multipack deals online.
15. Modibodi Active Brief With Front Pocket (Women)
Period underwear that also carries your essentials? Modibodi’s Active Brief ticks both boxes, wrapping leak-proof tech and a stealthy stash slot into a low-rise silhouette that disappears under leggings.
- Built-in absorbent gusset holds up to 2 regular tampons worth – ideal for light-to-moderate flow days, sweat or stress leaks.
- Slim front slip pocket sits just below the waistband; big enough for a tampon, house key or credit card yet flat enough that it won’t print through bike shorts.
- Outer fabric is a moisture-wicking merino wool blend backed by recycled Polybrush™ lining, so the brief stays cool even in 30 °C heat.
- Odour-controlling treatment keeps you fresh on long commutes or spin class.
Best for runners, cyclists and gym-goers who’d rather go bag-free but still need leak security. Sizes range XXS–6XL and, at roughly AUD $34, it’s one of the most inclusive, multifunctional pieces of underwear with pocket convenience on the market.
Choose Your Pocket Wisely
A zipped security pocket is the Fort Knox of underwear—perfect for passports and cash on an overnight train. A stitched-in stash sleeve keeps a single card or key flat against the thigh, ideal for 5 km runs or coffee dashes. Pouch dividers, meanwhile, pull double duty: they lift the lads for chafe-free comfort and will also grip a folded note in a pinch.
Before you hit checkout, match fabric to climate (bamboo for muggy summers, nylon blends for sink-washing on the road) and measure the item you plan to carry—there’s no point buying if your car fob won’t fit. Finally, map out your rotation; three-packs often drop the per-pair cost by 20–30 %.
Need the lot—eco fabric, anti-chafe pouch and a stealthy pocket? SLY Collective has you covered.
