A mitten that can be split into two gives you terrific flexibility. The Swany Extreme 2N1 Women's Mitt has an inner nylon mitten liner with 400 grams of Insuloft Hipora® on the back of the hand, 300 grams on the palm, and a waterproof breathable membrane to keep your hands comfortably dry when you’re out in the cold. Popped into the outer mitten with its LeatherShield palm and Polartec NeoShell softshell back of hand you’ve got a powerful combination against winter that can be boosted by dropping a heat pack between the two so you get the benefits of the extra warmth without the heater sitting on your skin. A two-for-one combo that will take you from one end of winter to the other in flexible comfort.
