The Western Mountaineering Alder MF 25 Degree Sleeping Bag is for those mild nights when counting shooting stars is all you have to do. The the semi-rectangular Alder MF is your bag of choice! Roomy enough for comfort and warm enough so you won't wake with a chill before dawn. This bag has a 62" shoulder girth and 46" at the foot. The Alder MF has a zipper along the side so that it can mate with mummy bags and a zipper around the foot so that it can be opened flat as a comforter or zipped to our Summer Coupler to be a sleep for two. This bag was formerly known as the Aspen MF. Nothing about the bag has changed except the name.
