Marmot Zeus Down Jacket - Men's - $97.48

The Marmot Men's Zeus Down Jacket won't make your mountainous ascent any faster, but thanks to the fact that this jacket weighs only ten ounces and packs into its own pocket, you sure won't have to worry about sacrificing warmth to shave weight from your pack. You won't find the extra bells-and-whistles other down jackets boast, but the Zeus wasn't designed for pure luxury; it was designed to provide powerful warmth for backpackers, skiers, and climbers in search of a simple but effective insulating layer. - $97.48
