Space Cowboy™ Sleeping Bag 45F / 7C


SKU: 259438

Warm weather sleeping bag with water-resistant eraLoftTM 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 eraLoftTM 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 SynergyLinkTM 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.

  • Recycled Shell & Liner: GRS-certified 100% recycled fabrics are eco-friendly while being lightweight, soft and durable; anti-snag YKK zipper ensures easy entries and exits and prevents tears.
  • eraLoftTM insulation: Efficient and compressible, our 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.
  • SynergyLinkTM Connectors: Ultralight straps create a secure bag-to-sleeping pad connection that optimizes the comfort and thermal efficiency of your entire sleep system.
  • 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.

Combo stuff and storage sack included.
