The 4K elbow pads are a lightweight version of the higher end models and made for slightly less physical play. These elbow pads still feature the JDP elbow cap to disperse the force of impact away from the fragile elbow joint. X-Crossing comfort strap and lock system provide a comfortable system that holds the pad to the forearm while the non- stretch lock strap secures the elbow deep into the cap. A molded PE bicep cap provides a high level of protection for the bicep.
