These ski pants stay warm even in the freezing cold. The 3L fully seam-sealed construction makes them waterproof and windproof, while the inner layer uses high-efficiency insulating material to retain heat and wick away sweat. Breathable zippers on the inner thighs allow for rapid heat dissipation during high-intensity skiing. Detachable straps and an elastic waistband ensure a secure fit, and side zippers at the cuffs make it easy to slip on ski boots. A detachable snow skirt at the waist and an inner snow skirt at the cuffs provide double protection against powder snow.
