Global Glove Cow Grain Leather Driver Gloves feature an ergonomic keystone thumb that improves durability, comfort, and dexterity and reduces hand fatigue. Made with an Aralene (Aramid fiber) cut-resistant inner shell, the gloves display excellent cut and heat-resistant properties. The overcast color on the hem of these gloves allows for easy size identification, and an open cuff enables easy donning and removal. The Aramid fiber enhances the overall strength of the gloves and makes them ideal for performing hazardous industrial tasks. The gloves support ANSI level A4 cut protection and are tested to meet ASTM F2675 specifications.
