Why Debriefs Is Changing the Way Aussie Blokes Buy Underwear
Finding the best men’s underwear in Australia shouldn’t be a mission. You want comfort, breathability, and a fit that actually lasts. Not a waistband that folds over after three washes or fabric that feels like sandpaper by summer.
That’s where Debriefs steps in.
We make premium men’s underwear using MicroModal, a fabric softer than cotton, more breathable than bamboo, and ethically produced in Europe from beech trees. It’s the kind of underwear you forget you’re wearing... until laundry day, when it’s all you want to wear.
Soft. Supportive. Breathable. Built to Last.
Our undies are made for real daily wear. The workday, the weekend, the workout. Whether you’re after boxer briefs for support or trunks for freedom of movement, every pair is designed to stay put, breathe easy, and keep you cool (literally and figuratively).- No ride-ups
- No saggy waistbands
- No synthetic itch
- Just ridiculously comfortable underwear
Sustainably Made. Ethically Produced.
We don’t cut corners, and we don’t cut costs at the expense of people or the planet. Debriefs are manufactured in Turkey, in a facility that meets global ethical standards. We use biodegradable mailers, long-lasting fabrics, and we avoid the harmful pesticides and water waste of cotton production. It’s underwear that feels good, and does good.Got a question?
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.
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.
Once you try it, you'll wonder how you ever managed without it.
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.
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.
