Leather Drivers Gloves offer protection from rough objects, sparks and heat, and cushioning from blows in heavy-duty work environments. Cowhide is the most common type of leather glove. The advantages of Cowhide include comfort, durability, excellent abrasion resistance and breathability. The Grain Leather (on the palm) is the smooth external side of the hide. This type of leather provides durability and dexterity. The Split Leather (on the back) is the rougher internal side of the hide. This type of leather provides added breathability. Keystone thumb features a separate inset thumb with a double layer of leather for more protection, dexterity and comfort. Slip-on cuff allows for easy donning.
