RockFloss is a new, reusable simple, latex elastic band that can help you move better and with less pain. It comes in a roll packaged in a stiff cardboard box that fits easily in your gym bag or backpack. It's easy, convenient and reusable, and available in 2″ or 4″ widths. RockFloss uses the science of compression and fascial shearing to help 'unstick' muscles and joints so they move better and with less pain.
