The Mammut Sphere Down 3-Season is a high end performance and lightweight down sleeping bag with one of the lowest pack volumes available.
Made from extremely lightweight materials and with 450g of 800 cuin top quality European goose down, the Mammut Sphere Down 3-Season is a contender for being one of the lightest sleeping bags with the lowest pack volume on the market. The outer fabric is windproof and water repellent, whilst the wave-shaped chambers prevent the down from migrating. The two-layer 9-chamber construction and ergonomically designed foot areas in the winter versions and this 3-season model ensure increased comfort, insulation and extra warmth for your feet, and a 140 cm long zipper, makes getting in and out a breeze.
