The Reebok 16K elbow pads are constructed using a kinetic fit so that they conform to the shape of the elbow for a comfortable fit. The elbow caps use JDP which is Joint dispersion protection. This functions by dispersing the force of impact away from the fragile elbow joint to assure complete protection. The liner features ventilation and padding for cool comfort. Molded PE foam at the bicep, plus molded PE slash guards at the forearm offer great coverage from impacts and slashes. A crossover lock strap system securely holds the elbow pads in place during use.
