Durable, soft and extremely warm mittens knit with Buffalo Gold's bison down yarn. These mittens are absolutely fabulous! The buffalo down yarn makes a durable, super warm and extremely soft fiber. Our de-haired bison down yarn is used to knit wonderfully light, believably durable, washable, wear-it-everywhere mittens. The American bison down traps your body heat within the air pockets next to your skin. Bison mittens will allow your fingers to be enclosed together, allowing you to generate and maintain more heat than if they were each covered separately in a glove. Mittens are great for the extremely cold weather. The high moisture regain properties (the ability of the fiber to hold water without you feeling it) adds an even greater degree of comfort. For winter work, fishing, driving, walking, arthritic/medical heat retention to keep your hands warm. 90% Bison 10% Nylon. Made in upstate New York, USA exclusively for Buffalo Gold.
