BAPE Socks and Underwear

The word “trunks” isn’t just a stylistic choice — it’s a direct callback to boxing. In 1925, Everlast founder Jacob Golomb replaced boxers’ stiff, leather-belted shorts with a lighter, elastic-waist version to give fighters more freedom in their footwork. Clothing companies quickly repackaged a lighter version of that same design as everyday underwear, and the name “trunks” stuck around long after most people forgot it started in a boxing ring. BAPE’s own camo trunks carry that exact name today — a piece of underwear history hiding in plain sight on the product label.

Fabric Matters More Here Than Almost Anywhere Else

Socks and underwear sit closer to skin, for longer, than nearly anything else in a wardrobe, which makes breathability a bigger factor than it is for outerwear or accessories. Cotton remains the most breathable option for everyday wear, pulling moisture away from skin without trapping heat. Ribbed knit construction — used across BAPE’s sock line — adds a bit of stretch and grip around the ankle without needing tight elastic, which helps socks stay in place through a full day without cutting off circulation. For anyone shopping the rest of BAPE®’s camo lineup, matching sock and underwear material to the season works the same way it does for outerwear: heavier ribbed cotton for cooler months, lighter blends for summer.

Sizing Runs Differently Here

Unlike most BAPE categories, sizing for this collection isn’t based on height or a standard alpha size in the same way:

• Trunks (boxer briefs) size to actual waist measurement, similar to belt sizing logic — check the specific waist range listed on each product rather than assuming your usual pant size translates directly.
• Socks are largely one-size-fits-most within an adult range, thanks to the stretch built into ribbed knit construction, though it’s worth checking shoe-size compatibility on crew and ankle styles specifically.
• Sport bras run on standard band/cup sizing separate from anything else in the collection — always check the specific size chart rather than guessing from a t-shirt size.

Shop by Style

Camo Trunks — BAPE’s house camo prints on classic elastic-waist trunks, the piece most directly tied to the category’s boxing-ring origins.

Rib Socks — Ankle and crew-length socks in ribbed cotton knit, including logo, camo, and Baby Milo graphic styles.

Monogram & Pattern Socks — Statement designs like the “I Love Bape” monogram and BAPE STA prints, generally the most visible pieces in the category when worn with cropped pants or shorts.

Sport Bra — A single technical piece in the lineup, built for activewear rather than everyday base-layer use.

Making Elastic Last

The elastic in ribbed socks and trunks waistbands is the first part to wear out, well before the fabric itself does. Washing in cold water and avoiding high-heat drying extends elastic life significantly — heat is what breaks down the material fastest. Turning trunks and socks inside out before washing also reduces pilling and fading on printed camo designs, since the printed surface faces away from direct friction with other laundry.

Frequently Asked Questions

Q1: Why does BAPE call its underwear “trunks” instead of boxers or briefs? 

Ans: “Trunks” is the original name for this style, dating back to 1925 when it was designed for boxers before being adapted into everyday underwear — the name simply stuck.

Q2: How should I size BAPE trunks if I’m between waist sizes? 

Ans: Size up rather than down — a slightly loose waistband is more comfortable and less likely to lose elasticity quickly than one that’s stretched at its limit from the start. For the rest of the lineup, the full Accessories collection follows similar general sizing logic.

Q3: Do BAPE socks run true to size? 

Ans: Most ribbed styles are one-size-fits-most for adults thanks to their stretch, though it’s worth checking any specific shoe-size range listed on crew or ankle styles.

Q4: How can I make printed camo trunks and socks last longer? 

Ans: Wash in cold water, avoid high heat when drying, and turn pieces inside out before washing to protect both the elastic and the printed design.
