Comfort lives up to its name in several important and unique ways. It is cut a little wider than other mummy bags, which makes it less constrictive. Knees can be pulled up within the bag and there's a little more room around the torso for unrestricted movement. There's a separate zipper at the foot, which allows for ventilation in the night and makes it possible for the user to walk around camp while wearing the bag! (Let's face it, nobody wants to get out of their sleeping bag on a cold morning). To complete the conversion to a parka, there's a short zipper on the side of the bag opposite the main zipper, which then allows arms to be free for doing chores, eating a meal or sipping hot coffee. 

Available in three temperature ratings (15, 20 and 32F) and a women's version built with extra down insulation in the foot and torso sections for greater warmth and tailored to fit a woman’s frame - appropriately shaped for women’s shoulders (narrower than men’s) and provide more room in the hips (rather than a tapering from shoulders to feet in a men’s bag).
