Showa 310 Grip Glove, Seamless cotton/polyester liner. Adding polyester to natural cotton makes it possible to obtain a light supple liner. The natural rubber protects the hand from abrasion cuts, puncturing and extends the life of the glove. This coating also ensures excellent grip on both dry and moist objects, thanks to the rough finish. On this palm coated glove the knuckles remain free ensuring good dexterity, and the back of the hand is ventilated to reduce perspiration. Category: II Intermediate Design- reversible risks.
