Premium insulated performance gloves provide the widest temperature range possible by utilizing an Outlast® phase-change material liner. When your hands are cold, the liner acts like insulation and keeps heat in. When your hands get hot, it acts as a heat sink and pulls heat away. Additionally, when used with heated grips, it pulls the heat from the grips and distributes it around your hand. These are the only true insulated gloves that work with heated grips as most insulated gloves insulate you from the heat on the grips. Proudly handcrafted in the USA 2.75+ oz. deerskin (palm) and 4.0+ oz. elkskin (back) are more abrasion-resistant than cowhide Outlast® phase-change lining material changes its properties depending on temperature giving it an incredibly wide temperature range (30-70 degrees) Thinsulate Flex® on the backside of hand helps keep heat in without adding bulk to the palm side of the glove Trimmed and ironed internal seams provide unrivaled fit, comfort and dexterity Seamless palm for the ultimate in feel without pressure points Dual-duty thread provides the strongest seams and won't cut through leather like Kevlar thread.
