Unlike lesser models that lose power after only 6 1/2 hours, these are the gloves that provide up to 13 hours of 87°F heat on their lowest setting. On their highest setting, the gloves generate 126°F for 3 3/4 hours. Unlike stiff, clumsy models, these are made with a soft Thinsulate lining and waterproof material that provide soft interiors and flexible exteriors that make grasping items easier. Cinches at the wrist keep heat in and cold out, and a zippered, windowed pocket allows easy access to the battery and provides a quick glimpse at the temperature setting. A press of the battery’s large button changes the temperature to one of four levels. The 7.4-volt batteries recharge in four hours with the included AC adapter. Imported. Unisex sizes S/M (circumference of hand size at knuckles 7 1/2"-9"), L/XL (9-10 1/2"). (7 oz.)
