Stability design reduces rocking with adjustable sizing pad to assure proper fit. Heavy duty, over-sized, abrasion resistant, hard plastic cap with flat kneeling surface provides greater kneeling stability. Real gel insert does not compress over time, plus 1/2" foam padding absorbs impact and assures comfort. Hook and loop neoprene split strap avoids bunching. Unique sizing pads assure individual sizing comfort. Fully stitched polyester thread sewn on cap keeps debris out from under cap.
