We're Phillippa & Matthew, and we're changing how women purchase underwear!

At Flissie, we believe that comfort and convenience should never be compromised for style. That’s why we’ve created the most comfortable, stylish women's boxers that you’ll ever find. Our boxers are made from sustainably sourced bamboo fabric, making them incredibly soft and breathable, so you can feel comfortable all day long.

But we don’t just want to provide comfortable boxers. We want to be a source of good in the world. That’s why we’ve made it our mission to give back. For every 3 pairs of Flissie boxers purchased, we’ll donate 1 pair to female communities in need.

We’re redefining the way women purchase underwear and we’re doing it with a purpose. Join us on our mission to make the world a better place, one pair of boxers at a time.

Every 3 pairs sold 1 pair is donated to vulnerable women
