When ski mountaineers, alpinists, and climbers venture into the most demanding environments on earth, they rely on Arc’teryx outerwear to shield them from the elements. By employing the same performance fabrics and top-shelf design features of Arc’teryx’s technical outerwear, the Men’s Koda Insulated Jacket offers that same bombproof performance but in a street-smart package. The outer shell is a windproof and water-resistant fabric, and the Coreloft synthetic insulation is an efficient and non-bulky fill that offers superior warmth in the coldest conditions. Slightly less insulation at the underarms and side panels ensure a comfortable fit and a trim profile. Clean in looks, the Koda maintains a steam-lined design with just two hand pockets and an additional internal secure-zip chest pocket for valuables.
