The Nilas is a high-altitude belay jacket that is just as handy at lower elevation on cold days near big ice. It’s extraordinarily lightweight and packs down small for multi-day alpine trips. This is your new workhorse down coat. There are two unzipped pockets inside for gloves and food. Padded hand-warmer pockets are on the outside, and it has easy-to-use elastic cuffs with finger loops.
