The Mountain Hardwear Spearhead Mittens are a three-layer waterproof breathable shell that seals out snow and water and that come with a 200-weight fleece insert that offer great insulation. For 2009 this mitt is updated with new style lines and a logo screen print for increased durability. The Conduit Nylon Taslan shell is extrmeley durable and the water-resistant goatskin palm and fingers allow for increased dexterity. When the winter storms approach this mitt with a the fleece liner is a great combination and when the sun peaks back out you can use the fleece liner all by itself. Along with a full converage gauntlet, this is a true bomber mitten.
