What Our Gearhead® Experts Are Saying: "These are my deep-winter, storm-day mitts. The GORE-TEX Plus Warm insert is totally waterproof yet still breathable, and the PrimaLoft Gold insulation keeps my hands warm even on subzero mornings. The merino liner feels amazing, and the leather palm has all the grip I need for poles, shovels, or sled handles." We rely on the STIO Objective Insulated Mitten when the forecast calls for single digits and all-time snow. Designed for full days in harsh mountain conditions, it combines a stormproof GORE-TEX Plus Warm insert with 3oz PrimaLoft Gold Eco insulation to keep hands warm and dry no matter how deep the day gets. The merino wool-blend liner features individual finger compartments to boost warmth and comfort without sacrificing mobility. Full-grain leather palms and fingers add long-lasting durability and secure grip, while abrasion-resistant suede reinforcements hold up to seasons of wear. The waterproof, windproof, and breathable three-layer cuff seals out snow, and the adjustable gauntlet-style design fits easily over jackets. From early-morning tours to all-day storm riding, these mittens are built for those who don’t quit when the weather turns wild.
