Mira is a red giant star, estimated to be 200-400 light years away in the constellation Cetus.

  • Two flexible fabric bands keep your bag centered on your mattress. They eliminate problems with sliding, twisting and cold spots, yet still allow the head and foot to rotate freely and follow you just as they should. SynergyLink™ Connectors fit any mattress up to 25 inches (63 cm) wide.
  • The Mira™ women’s sleeping bag features concentrated, box-baffled down on the top and foot area to capture rising heat. A small amount of insulation in the bottom of the bag saves weight and prevents drafts, while your mattress provides full insulation from the ground.
  • This unique reflective lining captures your body’s radiant heat and reflects it back into your sleeping bag, adding up to five degrees of additional warmth without the weight or bulk of conventional insulation.
  • Therm-a-Rest® women’s sleeping bags are designed to follow the contours of your body, with extra volume in the hips and proportionately less in the shoulders, legs and length.
  • Ultralight 750+ fill goose down provides optimal warmth and compressibility for the backcountry. A 30D ripstop nylon shell balances light weight and durability, and is DWR-treated for maximum water and stain resistance.
  • Cold feet? No problem. Just slide them into this cozy, insulated oasis found in the footbox of every Therm-a-Rest women’s sleeping bag.

Temperature Ratings

Therm-a-Rest sleeping bags are rated to both US and European Norm (EN 13537) standards. All ratings are developed from procedures and testing conducted by independent organizations in the US and Europe. Sleeping bags and blankets without hoods are not subjected to EN testing.

  • EN Comfort: At this temperature, a standard woman can sleep comfortably in a relaxed position.
  • EN Limit: The lowest temperature at which a standard man will be able to sleep comfortably through the night. This rating is relatively close to those commonly used in North America.
  • EN Extreme: At this temperature, a standard woman can survive for at least six hours.
