Are your WOD's getting the better of your wrists? Need a little extra wrist support for that last muscle up? RockWrists were designed to provide the perfect combination of elasticity and support for optimal comfort and performance. Designed by Jason Khalipa, RockWrists are competition grade wrist supports, made from tough polyester fabric with strings that won't break and elastic that won't turn brittle, no matter how sweat-soaked they become. The hook and loop fasteners allow you to cinch them to the perfect tension level for your workout.
