The Highlands Sleeping Bag is a lightweight, compressible synthetic down sleeping bag for dogs, keeping them warm and comfortable on the trail, at camp, and in the backcountry. The half-length zipper maintains easy entry while reducing weight and bulk. When zipped closed, the design is efficient at keeping dogs warm - giving dogs room where they need it while tailoring the shape to cut down on extra space. A neck baffle folds in to keep cold drafts at bay and helps retain body heat. When extra insulation is needed, slip the Highlands Pad (sold separately) into the integrated pad sleeve as a barrier between colder surfaces. Compression sack is included.
