The Mammoth is the perfect bag for any family outing. Whether you are going for a weekend at the lake or your in-laws are staying over, this comfortable enough for two (maybe three or four if you have young children). Stash your personal items in the interior storage pocket for safe keeping, and pull the adjustable mummy hood down tight for extra warmth. There are also shoulder and zipper baffles to fight drafts. The oxford nylon compression sack makes this monster bag easy to transport and store. The bag is great for couples and families because of the full length zippers on both sides so you can exit the bag without disturbing your partner. The internal storage pockets on both sides for keys, wallet, watch and other valuables.
