The Heavy Duty Black Industrial Gloves come in either 35cm (halfway up the forearm) or 45cm (to the elbow) in length from the tip of the longest finger to the bottom of the glove. They are more than twice the thickness of the standard black industrials and provide great durability and protection in wet conditions. The rough finish on both the front and back of the hand has what can only be described as horizontal ridges of rubber that provide for exceptional grip in the wet. The inside of the glove is orange.
