Behind every pair of world-beating trousers, there should be a proper pair of underwear.

So we finally poured our fit expertise into the most important part of your wardrobe. Choose from 28 carefully calibrated sizes, when most brands will offer you six.

We’ve picked a blend of breathable lyocell and elastane, for extraordinary stretch and recovery — and the structure in this Portuguese weave creates a lush, soft hand-feel.

We’ve added a stay-put hem, to anchor these trunks, so you’ll feel all the support you are looking for — with none of the pinch.

Fit so good, you'll forget you're wearing them…

Our Trunks are 94% lyocell and 6% elastane.

Tom, our stuntman, is 6'2" and is seen here wearing size 32, with a 5" leg length.

It's worth noting 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.
