This Epi-lock Elbow Strap is uniquely designed and more effective and comfortable than conventional supports. Epi-Lock's unique distal strap supports extensors that are deeply buried and harder to support near the elbow where tennis elbow straps are usually worn, and two straps together give exceptional support and pain relief. The non-elastic straps are worn comfortably snug, so when muscular force is applied, the extensors automatically enlarge, causing the straps to tighten and focus the binding force for maximum effectiveness. Plus, this unique strap is lightweight, and the nonslip material is completely washable.
