Sierra Designs: Echo -20 Degree Sleeping Bag

From Everest to Elbrus, the Echo performs. Welded seam construction, an Expedition Jacket Hood, and 800-fill goose down guarantee warmth and safety in the harshest environments on earth. Funk!Off™ liner—simply turn the bag inside-out, leave it in the light and voila, dirt and oils magically break down for a cleaner, fresher bag. Waterproof-breathable DriZone™ keeps you, and your insulation, bone dry even in a snow cave. A storm flap over the reverse-coil zipper bars blowing or melted snow. Down to 20 below the Echo stays warm, conserving heat with dual draft tubes and the quiet, comfortable Expedition Jacket Hood. Don't risk your comfort and safety in big terrain—the Echo thwarts the elements and keeps you dialed with technical design and peerless function.
