The Cestus RockHard Original glove features a one-piece, goat-skin leather palm that is dual layered and reinforced with double stitching for durability. Padding in high-impact areas of the palm gives the user added protection, while the coarse zip grip saddle adds grip control and reinforces a high-wear area. Flexible Thermoplastic Rubber (TPR) shields cover the knuckles and back of fingers for protection that bends with the fingers and guards against light impacts, and lacerations. Back-of-hand, form-fitting spandex adds breathability to the glove, while the terry cloth backing on the thumb absorbs moisture and is for brow wiping.
