The Cliff Keen "Signature" 4-strap FOAM headgear is based on the revolutionary design of the original foam E-41 that Cliff Keen patented nearly 50 years ago. The Signatures' VNF foam boasts these same qualities that made it the best-selling eargaurd 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. For the Custom Signature, choose your strap color: Vegas Gold, Lt Gold, Orange, Scarlet, Black, Royal, or Navy. Allow 2 weeks.
