COOPER’S unique “3 in 1” system allows its components to be worn separately or together, depending on the weather. The outer shell of butter soft native deerskin, worn alone, is perfect for just above freezing days. The inner knitted glove of 100% Wool with lightweight sheepskin leather palm, worn alone, is warm and comfortable for driving or a long walk. When both gloves are combined COOPER becomes our warmest offering for the coldest days.
