The Details


It’s easy to make things lightweight. The challenge is to make them as light as they can be without going too far. Siren™ takes away everything extra without taking away the promise of a warm and draft-free night’s sleep. It is one of the lightest quilt-style sleeping bags on the market, constructed using the highest end fabrics and premium 850 fill power down.

The backless design straps directly to your sleeping pad, and is held in place with drawstring lacing that adjusts easily to accommodate different pad sizes. The stretch footbox anchors to the bottom of your pad, keeping it securely tucked in and minimizing drafts.

Best Use
  • Backless design shaves weight.
  • Lacing loops on the underside strap paired with a drawstring adjust system accommodate a variety of pad sizes and minimize drafts.
  • Drawstring opening keeps you tucked in and minimizes drafts.
  • Stretch footbox anchors around pad and keeps it securely in place.
  • 100% Responsible Down Standard (RDS) Certified down is traceable and ensures humane treatment throughout the supply chain.
What's Included
  • Compression stuff sack
  • Cotton storage bag
