Mens Underwear Australia - Shop MicroModal Trunks & Boxer Briefs

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.

No, it's a fly opening. We've bucked the trend and designed a fly in a horizontal layout because it's much more practical than a vertical fly. It gives you quicker, easier access when nature calls and eliminates the fumble you'd get with traditional fly designs.

Debriefs are made from 94% MicroModal™ and 6% Elastane. MicroModal™ is a sustainably sourced fabric that's produced from beech wood trees grown in Europe. 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.
