Behind every pair of world-beating trousers, there should be a proper piece of underwear. So we poured our fit expertise into your top drawer. 

For 2026, we went back under the bonnet. The fabric base is denser and tougher than before, without sacrificing the deep-stretch, moisture-wicking properties, or the lightweight wear.

Then there's the waistband. Now broader, sturdier, but even softer — supreme comfort, no ripple or roll. 

The anchoring thigh hems, lock in your fit with no squeeze, and zero mid-morning readjustments.

Choose from 30 size combinations: S to XXL, across three builds and two leg lengths, when most brands hand you six and call it a day.

Consider it fit, fine-tuned from the waistband down.
 
Our Trunks are 94% lyocell and 6% elastane.

Tom, our stuntman, is 6'2" and is seen here wearing size L, Build C, with a 5" leg length.

Note that due to hygiene reasons, underwear is exempt from our returns policy, and we will not be able to accept any pairs back for a refund or exchange.
