Sierra is about to take the zip out of the mummy bag. This bag is meant to be more bed than mummy.
With an integrated pad-pocket the base bag is not meant to move with you, but allows you to move within. Access is through the large opening. Comfort is provided by a separate comforter that can be tucked in or out as comfort and temperature dictate. Sierra is also going to offer an Ultralight Quilt, that will feature an integrated hood with hand and arm pockets. These and a Movable Mummy will all be revealed at the upcoming Outdoor Retailer Show. All of them stuffed with Sierra’s proprietary DriDown. We hoping to take them for a test drive.
