From Sydney Beaches to Your Top Drawer
Mosmann was born by the sand — inspired by the easygoing vibe of Sydney’s northern beaches. Sun on your back, salt in the air, nothing but laid-back living. We took that feeling and stitched it into every piece we make. What started with ridiculously comfortable underwear has grown into swimwear and everyday essentials — all designed to feel like a holiday, even when you’re not on one.
Underwear That Feels Like Nothing Else
At Mosmann, we believe your first layer should never be an afterthought. That’s why our underwear is crafted from luxuriously soft bamboo — a fabric that breathes, moves, and keeps its cool no matter what the day throws at you.
We’ve taken the everyday essential and elevated it: tailored fits that don’t ride up, waistbands that stay put, and a feel so smooth it’s like wearing nothing at all. Bamboo also happens to be naturally sustainable, so you get comfort with a conscience.
Slip into a pair and you’ll know — this isn’t just underwear. It’s Mosmann: effortless, modern, and designed to make you feel your best from the inside out.

Swim Shorts With a Holiday Built In
Mosmann swim shorts aren’t just for the water — they’re built for the lifestyle that happens around it.
Crafted with quick-dry, 4-way stretch fabric and finished with our signature details (yes, even the sunglasses-shaped zipper puller), they’re made to move seamlessly from surf to street.
Every pair is designed with comfort at the core — ultra-soft mesh lining, a fit that feels tailored without being stiff, and fabric that dries before you’ve even finished your post-swim drink.
More than swimwear, they carry the spirit of escape: rooftop pools in New York, beach bars in Bali, or backyard BBQs at home. With Mosmann swim shorts, you don’t just wear them — you live in them.
