The Highlands Sleeping Bag is a packable, durable sleeping bag provides warmth and comfort for your dog on the trail or the camp site. The zippered opening allows the bag to open wide, then zip closed to retain dogs' body heat. Lightweight synthetic insulation provides warmth and protection from hard, cold surfaces and compresses into an included stuff sack. Integrated pad sleeve accommodates the Ruffwear Highlands Pad (sold separately) for additional insulation in extreme cold. Durable polyester fabric shell provides a comfortable sleeping surface and cleans with a shake.
