The Sierra Designs Backcountry Bed 800 is an innovative design that combines good attributes of traditional mummy style sleeping bags and an ultralight quilt. While certainly not ultra-light, this bag is ultra-comfortable. The unique "bed-style" design of this bag enables you to manage temperature easily and roll around with the attached quilt to your perfect sleeping position. Stomach sleepers like this bag for the ability to lay flat on their stomach with their arms pointing toward their head, still within the warmth of a down sleeve/pocket. This bag is not the overall best performing sleeping bag in this review but for those who prioritize comfort over weight and materials, the Backcountry Bed is a good choice. We can only hope that this bag gets lighter in future versions so that we won't hesitate to take it on summer backpacking trips.
Sierra Designs updated their line of Backcountry Beds. For our review of one of the new versions, check out the Sierra Designs Backcountry Bed 700.
