Mens 100% Shearling Sheepskin Winter Mittens. Soft suede leather finish with a silky soft & warm natural sheepskin wool inner. Natural sheepskin is soft and light, amazingly warm and exceptionally durable. No natural or man-made fiber possesses the virtues of 100% shearling sheepskin. The unique combination of leather skin on one side and wool fur on the other lends it remarkable properties. Sheepskin wool is soft and resilient. Its fibers breathe, acting like a natural thermostat for your body. These hollow fibers can absorb up to 30% of their own weight in moisture without feeling wet, keeping you perfectly dry regardless of the weather. The free flow of air between you and the sheepskin fibers is a comforting change from the clamminess of leather and vinyl.
