Basecamp Down Sleeping Bag The Basecamp takes vehicle-based camping to the next level. This version of the Free-Flow Zip system allows you to open either side of the bag or the footbox for the greatest ventilation possible. 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-PFAS 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 favourite pillow from home. If you're looking for one of the best, most comfortable vehicle-based sleeping bags available, look no further.
