With a WHOOP 5.0 band, you can give your WHOOP One or Peak their own look and you can comfortably wear it around your wrist. These bands only fit on the WHOOP One and Peak because of the 5.0 sensor. The band is easy to attach to the sensor. You can easily adjust the size yourself, so the band always fits well. Go for a leather strap when you wear it to a fancy occasion. Usually use it during a workout? Choose a silicon band.
