We took our men's brief style and put them in a new extra breathable fabric that will keep you cool and dry all day. So soft and comfortable, you might forget you're wearing them. Made with a lightweight sports mesh (but it's so fine, you can't even tell it's mesh), this is our most breathable underwear yet. It's got all the things you loved about our other briefs but gives you even more air...down there. Also, it's made with Recycled PET (think: plastic bottles), so it's eco-friendly, too.
