The 5/8" thick Hanging Mats are 6 millimeters thicker than other hanging mats, providing more support for your joints. These dense, high-quality closed-cell foam mats are light yet resilient, perfect for low-impact exercise, core training and stretching. They maintain their shape and stay flat on the floor whether you hang, stack or roll them after use. Reinforced plastic grommets won't harm floors, rust and won't bend or deform when stepped on. Available in two lengths. Sold individually.
