If a ski coat that summited Everest during a trial test can't keep you warm, nothing can. The Spyder Eiger is prepared to take you skiing, mountaineering, ice climbing and winter camping without ever catching a chill. Designed by professional athletes Chris Davenport and Stian Hagen, this jacket is made out of stretch nylon and equipped with top-of-the-line exhaust vents around the front collar to monitor moisture. EVA foam inserts around the bottom hem prevent the jacket from riding up and bunching when you put a harness on. Its chest and hand pockets are situated in a way that is backpack compatible so you can access them without having to shift your pack. Like any good mountaineering jacket, it has a RECCO strip to aid workers in the case of an avalanche and fully taped seams to maximum warmth and wind protection. The Spyder Eiger has an adjustable draw cord collar, as well as one at the hem. Beyond all this, it has a removable powderskirt and a hood that can fit a helmet inside. If you are a serious mountaineer or winter adventurer, you need the Spyder Eiger jacket as your first companion on trips.
