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.
