Therm-a-Rest Space Cowboy 45F/7C sleeping bag

Warm weather sleeping bag with water-resistant eraLoft™ insulation for durable and lightweight performance at a great value

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, GRS-certified 100% recycled 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.
