Therm-A-Rest Space Cowboy 45

Built to explore the last frontier, the lightweight Space Cowboy is a favorite for summer backpackers and cowboy campers.

The mummy-style bag compresses down to take up minimal room in your pack and comes in two outdoor-inspired colors. Whether exploring the western frontier, bike packing through the desert or wandering through the wild, the Space Cowboy has you covered. Storage sack and compression stuff sack included.
