Every high-altitude ascentionist seeks a layer with these three key factors: warmth, light weight, and windproofing. Designed for alpinists of every level, the Nilas™ features responsibly-sourced, ultralight down that resists moisture to retain critical loft and warmth even in damp conditions. It keeps the wind at bay, so even when it's howling, it's always calm and dry inside.
