The Therm-a-Rest Space Cowboy 7°C – Long is a lightweight, packable, and eco-conscious synthetic sleeping bag built for warm-weather adventures. Whether you’re bikepacking, thru-hiking, or summer camping, this bag delivers dependable comfort and fast-drying insulation—ideal for humid, dewy, or mildly cool nights under open skies.

Designed for minimalist performance, the Space Cowboy features eraLoft™ synthetic insulation, which retains warmth even when damp and compresses efficiently for easy packing. The mummy-style cut increases thermal efficiency without restricting natural movement, while the anti-snag YKK zipper, full-length draft tube, and anatomical shaping enhance overall comfort and heat retention.

Made with 100% recycled nylon RipStop, both the shell and lining include a DWR (Durable Water Repellent) coating to shed light moisture. The Long version is designed for taller users (up to 198 cm), offering more length and shoulder room without significantly increasing weight or packed size.
