Soft enough to forget you're wearing them. Tough enough to last years, not months. Our trunks are cut short in the leg so they disappear under whatever you're wearing: jeans, suit pants, shorts. The Lenzing MicroModal fabric is sourced from sustainably grown beechwood in Austria and feels nothing like cotton. It's softer, lighter, more breathable, and it lasts. Pair after pair, wash after wash.

What are men's trunks?
Men's trunks are a fitted style of men's underwear with a shorter leg that sits mid-thigh. They give you support without extra fabric, which is why they work well under jeans, shorts, chinos, and work pants. Debriefs trunks are made from MicroModal, a fabric 3x softer than cotton. If you want more thigh coverage, see our boxer briefs.
Should I choose trunks or boxer briefs?
Trunks have a shorter leg and stay out of the way. Boxer briefs give you more coverage and help reduce ride-up if you prefer extra leg. For the full comparison, read our guide to trunks vs boxer briefs.
Are Debriefs trunks made from cotton?
No. Debriefs men's trunks are made from MicroModal, which feels softer, breathes better, and handles moisture better than standard cotton. It's produced by Lenzing in Austria from sustainably managed beechwood. You can compare fabrics in our cotton vs bamboo vs modal guide.
