Insulated with water-resistant synthetic insulation and employing a number of thermally-efficient and comfort-enhancing features, the Therm-a-Rest Space Cowboy 45 Degree sleeping bag delivers all-condition summer and warm weather backpacking performance.
The bag utilizes eraLoft synthetic fill, a lightweight, compressible insulation that better retains its ability to keep you warm even when wet than does down insulation. Recycled nylon ripstop shell and liner fabrics also help to protect against the elements. Additionally, the bag has "zoned" construction, concentrating insulation on top of the bag so you have warmth where you need it most and saving weight by minimizing insulation on the bottom of the bag where it just tends to get compressed beneath the weight of your body anyway. Together, these features grant the bag its 45 degree Fahrenheit temperature rating. Other features include snag-free zippers and integrated SynergyLink Connectors that secure the bag to your sleeping pad (pad sold separately) to keep you settled in place throughout the night and maximize the efficiency of your sleep system.
The Therm-a-Rest Space Cowboy 45 Degree sleeping bag is available in your choice of Small (fits up to 5' 6"), Regular (fits up to 6' 0"), and Long (fits to 6' 6") lengths. A stuff sack and storage sack are included.
