Grenade Apache Mittens are strong and durable, including a fingertip cover that makes the mitten very resilient. The material is a polyester blend finely stitched together, water resilient, which makes it ideal for snowboarding and skiing. The added fingertip and thumb leather creates optimal grip for outdoor winter sports. The additional material covering the fingertips and thumb also helps to insulate the most vulnerable part of the hand against frostbite. The mittens can be customized with a breathable, waterproof insert.
