Therm-a-Rest Space Cowboy Sleeping Bag

The Therm-a-Rest Space Cowboy is a lightweight, synthetic-fill mummy sleeping bag intended for warm-weather backpacking. It suits hikers and backpackers who want a compact, quick-drying bag made from recycled fabrics.

Key features

• Limit temperature: 7 °C (45 °F) — designed for warmer nights.
• eraLoft™ insulation: water‑resistant polyester hollow‑fiber that maintains loft in light dampness.
• Recycled nylon shell and lining: both fabrics made from 100% recycled nylon for reduced environmental impact.
• Performance Fit: mummy profile with modest internal space for comfort without excess bulk.
• Multiple sizes: available in S / R / L to match user height and save weight.

Space Cowboy is intended for spring and summer use or generally warmer nights on multi-day hikes and camps. Its synthetic fill makes it better suited to damp conditions where fast recovery of insulating properties and drying are important.
