The world’s most comfortable brace made from premium natural materials. The mineral-lined fabric returns far infrared (FIR) energy to your body to restore your muscles faster while a strong, stabilizing design helps you recover faster. FIR is proven to provide relief from strains, promote blood circulation, and reduce muscle tension and swelling. The jumper’s knee strap features tubular inserts to help with patellar tracking with only mild pressure on the tendon below the knee.
