The new Cliff Keen Signature, which is a 4-strap FOAM headgear, is based on the revolutionary design of the original foam E41 Traditional Wrestling Headgear that Cliff Keen patented nearly 50 years ago. The "Signature's" VNF foam boasts these same qualities that made it the best-selling ear guard of all time: Lightweight, more comfortable fit and greatly reduced friction on the mat. Fully adjustable. SP94 chin strap pad included. Can be adjusted to fit youth sizes too.
