The underwear

Trunks have a short leg, boxer briefs have a long leg.
If you're an active guy, or you have larger legs, we recommend choosing boxer briefs. If you have a sedentary lifestyle, work behind a desk, or have thinner legs, we recommend choosing trunks.

Debriefs are made from 95% MicroModal™ AIR and 5% Elastane. MicroModal™ AIR is a sustainably sourced fabric that's produced from beech wood trees grown in Austria. The added Elastane provides extra stretch for a snug fit that moves as you do.

Debriefs are made in Turkey by our GOTS certified manufacturer. The MicroModal™ AIR we use is sourced from Lenzing in Austria.

We’ve gone to great lengths to ensure we work with sustainable and natural materials where ever we can. MicroModal™  AIR is a sustainably sourced fabric that is 100% biodegradable. It's one of the most sustainable fabrics in the world and supersedes cotton with it's eco-friendly qualities.

All of our manufacturing partners are GOTS certified and abide by sustainable production practices.

We also use 100% biodegradable mailing satchels, and carbon neutral shipping providers.
