The Wells Lamont HydraHyde work mittens are designed with both functionality and warmth in mind. HydraHyde leather makes the mitts water-resistant, while the 150-gram Type C 3M Thinsulate insulation keeps your hands warm and dry. Durable grain cowhide leather is resistant to abrasion and the extra wear palm patch offers enhanced grip. The mitten liner allows fingers to huddle together and stay warm. The slip-on knit wrist cuff can be worn inside or outside the mitt. Wells Lamont - Stubborn About Quality Since 1907.
