Performance Underwear

Our game-changing Performance Series is the ultimate premium underwear for active sports, combining two patent-pending technologies. The innovative X-Fly provides fast and easy access, and our Coccoon internal support system minimizes chafing and provides optimal comfort and support. Extra features like the ZeroFold 360 ensure the waistbands stays in place while you focus on your game.

Crossfly has been a vision of a small team of sporting product professionals from the UK and America. Together, we have acquired decades of experience working in the Sports industry for global brands within Marketing and Product Innovation. After a few false starts, some legal issues, a eureka moment, and a global Pandemic Crossfly was finally ready to get going.


WE'VE RAISED THE BAR and deliver the most comfortable underwear and socks you will ever wear; packed with patent pending technologies and features that offer ultimate comfort whatever you're doing. GAME. CHANGED.
