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 1 kg and with a comfort rating of 7 °C, 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.
Combo stuff and storage sack included.
- Recycled Shell & Liner: GRS-certified 100% recycled fabrics are eco-friendly while being lightweight, soft and durable.
- eraLoft™ insulation: Efficient and compressible, proprietary synthetic insulation uses hollow fibers to trap air and boost warmth without added weight; dries fast and retains loft and warmth even when wet.
- SynergyLink™ Connectors: Removeable ultralight straps create a secure bag-to-sleeping pad connection that optimizes the comfort and thermal efficiency of your entire sleep system. SynergyLink Connectors function best with regular sized sleeping pads that are 3 inches thick or less when inflated.
- YKK® Anti-Snag Zipper: Prevents accidental tears and eases entries and exits.
- Heat-Mapped Zoned Insulation: Delivers an elite warmth-to-weight ratio by allocating insulation to where you need it and reducing it where you don’t.

Therm-a-Rest
In 1973, the first self-inflating air mattress was launched under the brand name Therm-a-Rest, which was the joint effort of Jim Lee, Neil Anderson and John Burroughs, former Boing engineers. In 1972, they founded Cascade Designs in Seattle, under which the world's first self-inflating sleeping mat was manufactured and sold. In the following years, Cascade Design obtained patents for their solutions and continually innovated their product range - in 1986 they introduced a unique foam mattress, in the following years sleeping bags, lighter self-inflating mattresses, air pads with an extremely high R-value, and in 2020 patented valves for the mattresses.
Cascade Designs also markets high-end outdoor products under other brands such as MSR, Platypus, PackTowl, SealLine.
