As the proud title partner of the UCI Mountain Bike World Series, we’ve released two new HydroKnit band colors — Bail and Downhill. Whether you live to send it or just love HydroKnit’s sweat-wicking properties, these bands are a great, fast-drying option to add to your collection.

The HydroKnit band is a sleek, fast-drying fabrication that’s a fan favorite for a reason. It dries twice as fast as SuperKnit and retains 30% less water – making it a must-have for water sports, high-sweat activities, or just taking a shower. 

Includes Band, Hook, Clasp, and Fast Link™ slider that makes swapping bands easier than ever. Only compatible with WHOOP® 4.0.
