What Our Gearhead® Experts Are Saying: "These mittens are my go-to for freezing powder days. The GORE-TEX insert keeps my hands completely dry, the HeatLock insulation packs serious warmth, and the plush lining makes them super comfortable. The one-handed cinch is a lifesaver when I need to tighten them up on the lift." We reach for the Seirus Phantom GORE-TEX Mitten when temperatures plummet and the snow starts dumping. The GORE-TEX insert provides full waterproof, windproof, and breathable protection, ensuring our hands stay warm and dry no matter how wet the weather gets. Inside, 200 grams of HeatLock premium hollow-core insulation trap body heat efficiently, while the plush Hydrowick lining wicks moisture to keep our hands comfortable during high-output runs. The durable Pro fabric shell stands up to the demands of the mountain, and the ToughTek palm delivers a confident grip on poles, tools, or gear. With a one-handed wrist and cuff cinch, we can quickly seal out snow and biting wind without pulling off our mittens—keeping us focused on the next line.
