With a relaxed semi-rectangular fit, for even more space you can zip two Basecamp sleeping bags together as a double, or unzip the upper section for use as a quilt. RDS-certified, 650+ fillpower duck down with a non-PFC Ultra-Dry Down treatment, a box baffle construction with vertical chest baffles in the torso for reduced down movement, and a hood large enough to accommodate your favorite pillow from home.
