Therm-a-Rest SpaceCowboy 45F/7C Sleeping Bag Regular celestial

The Space Cowboy sleeping bag welcomes the idea of sleeping out under the stars with the worry-free warmth of synthetic eraLoft insulation. Its hollow fibers allow it to retain warmth even when wet—shrugging off morning dew and drying out super fast. Weighing less than two pounds and with a comfort rating of 45F/7C, you’ll be plenty warm all summer, whether you’re road tripping or heading deep into the backcountry. Shell and liner are made of a light and soft, nylon and an anti-snag YKK zipper keeps them free of accidental tears. For optimal efficiency SynergyLink Connectors mate the bag to your sleeping pad, preventing drafts and cold spots. The precision-tuned fit makes sure you have the space you need, while eliminating unnecessary drafts and weight.

EraLoft synthetic insulation
EraLoft is a highly efficient and compressible synthetic insulation. It is made of microfibre polyester. The core of each fibre is hollow, optimally retaining body heat while weighing less.

SynergyLink Connectors
By integrating the mat and sleeping bag, the SynergyLink Connectors ensure that you don't roll off the mat while sleeping - without constricting. Two elastic straps can be adjusted to fit any mat up to 63.5 cm wide.
