What Our Gearhead(R) Experts Are Saying:"I've worn the Haldigrat GTX HS Thermo Pant on storm days at the resort and windy midwinter tours, and it hits a great balance of warmth and mobility. The GORE-TEX shell blocks moisture completely, while the Polartec Alpha insulation keeps me warm without overheating when I'm moving. I really appreciate the side vents for dumping heat and the reinforced cuffs that hold up to sharp edges day after day."We rely on the Haldigrat GTX HS Thermo Pant from Mammut when winter throws unpredictable weather our way. From frigid chairlift rides to cold, windy transitions in the backcountry, these pants keep us warm, dry, and focused on the descent instead of the conditions. The fit feels dialed for skiing and snowboarding, giving us freedom to move without excess bulk. Built around a recycled GORE-TEX shell and breathable Polartec Alpha insulation, the Haldigrat GTX HS Thermo Pant blends waterproof protection with active warmth. Fully taped seams seal out moisture, while zippered thigh vents let us regulate temperature on high-output climbs. Reinforced cuffs and ski-edge protection boost durability, and the adjustable waist delivers a secure, comfortable fit for long days in winter terrain.
