Exceeded my expectations
I hadn’t heard of Proper Men before, so I was a little hesitant at first. But the quality is really good. Pleasantly surprised.

SO LIGHT YOU’LL ALMOST FORGET YOU’RE WEARING IT
Many boxers feel heavier than they need to: thick fabric, warm spots, seams that chafe, and legs that ride up throughout the day. Especially when it’s hot or you’re moving a lot, you quickly notice that your underwear is there.
AeroFit is specifically designed to reduce that feeling as much as possible. The ultra-thin, silky-soft fabric fits smoothly against your body, moves with you, and feels almost weightless.
No heavy fabric. No sticky feeling. No constant distraction. Just maximum comfort, all day long.
THE THINNEST BOXER ON THE MARKET
AeroFit is made from extremely thin and lightweight material that is barely noticeable against the skin.
The fabric fits closely without feeling heavy or restrictive, making the boxer feel almost like a second skin.
STAYS COMFORTABLY IN PLACE
The boxer molds to your body and stays securely in place while walking, sitting, and moving.
Thanks to its high elasticity, it stretches easily with you without losing its shape or feeling restrictive.
SILKY-SOFT AND SMOOTH
The smooth material feels exceptionally soft and glides comfortably over the skin.
Thanks to the seamless, minimalist finish, there are fewer hard edges and seams that can chafe or irritate.
BREATHABLE AND COOLING
The thin, airy fabric helps release heat faster and allows your skin to breathe more easily.
This helps keep things cooler and drier down there, with less of the warm, sweaty feeling you often get with thicker boxers.
EXTREME STRETCH
The combination of nylon and elastane gives AeroFit plenty of stretch in every direction.
As a result, the boxer moves smoothly with your body and feels comfortable for both everyday wear and more intense movement.
