This knee wrap stimulates blood circulation, promoting relief from arthritic pain while you perform your daily routine or while you sleep. The wrap exerts a gentle compression and warms the surface skin, facilitating blood flow throughout the knee to reduce swelling, improve the mobility of joints and ligaments, and help relieve arthritic pain. The wrap is made from a flexible nylon/neoprene material that allows a full range of motion, and fastens with an adjustable hook-and-loop closure for a personalized fit and compression variation. The wrap's patented lining wicks away moisture and allows the skin to breathe to ensure comfort during extended wear. For proper sizing, measure circumference of the knee slightly bent, underneath kneecap. Hand wash. Specify unisex sizes.
