Collection: Trunks — the ultimate everyday essentials Organic cotton (95%) and TENCEL™ Lyocell.

Men's trunks in 95% organic cotton or TENCEL™ Lyocell

Our trunks are four styles: the Core Trunks and the Core Icon Rib Trunks in 95% organic cotton with elastane, the Premium Trunks made with TENCEL™ Lyocell fibers, and the Core Play Trunks. A trunk sits shorter in the leg than a boxer brief and closer than a boxer short, which is the whole reason the cut exists.

What is the difference between trunks and boxer briefs?

It is the leg. Both are fitted, but a trunk stops high on the thigh while a boxer brief carries on down it. If you want the fitted feel without fabric at the mid-thigh, these men's trunks are the shorter answer; if you want more coverage, the boxer briefs are the longer one.

The cotton pair, and the rib

The Core Trunks are the plain cotton style, at 95% organic cotton with elastane. The Core Icon Rib Trunks are the same composition in a ribbed knit rather than a flat one, with the logo at the waist. The Core Play Trunks are 95% organic cotton as well.

The Premium Trunks

The Premium Trunks are made with TENCEL™ Lyocell fibers and elastane instead of cotton. That is a different feel rather than a better one: the fiber is smooth and drapes. TENCEL™ is a trademark of Lenzing AG.

Sizes and the rest of the drawer

Sizes run XS to XXXL on nearly every style. Each product page carries the exact composition for that trunk, because the cotton styles and those made with TENCEL™ Lyocell fibers are not interchangeable on fabric even where the cut matches.
