Kelp Hydroknit Band

The all-new HydroKnit band is our fastest-drying, most advanced fabrication yet. 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. The performance-ready, water-resistant band comes in four colors: Riptide, Night Swim, Tidal, and Wipeout.

When you purchase the HydroKnit band, a portion of the proceeds go toward the Michael Phelps Foundation (MPF) to promote water safety. Since its founding in 2008 and with the help of strategic partnerships, MPF has provided critical, live-saving programming to more than 350,000 people worldwide.

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