Capella is the brightest star in the constellation Auriga and the sixth brightest star in the night sky. Its light actually comes from two separate stars.

  • 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 Capella™ 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.
  • EraLoft™ is a proprietary blend of three synthetic fibers that provides superior warmth, loft and durability. Short, soft fibers trap warmth, long fibers create loft and medium-length fibers provide structure and water 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.

  • 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.
