Now featuring Nikwax Hydrophobic Down, the Mira women’s down sleeping bag is the all-around winner for ultralight three-season backcountry adventures. Its temperature range hits the sweet spot for keeping you warm on everything from low elevation spring thru-hikes to late summer high alpine traverses. An unrestrictive women’s-specific cut shifts volume from the shoulders to the hips to maintain warmth. In addition, key features like our Toe-asis Foot Warmer, ultralight and compressible 750+ fill Hydrophobic goose down, reflective ThermaCapture lining and mattress integration assure you’ll stay warmer, sleep better and go farther with less to carry.
  • Zoned Insulation (Box-baffled 750+ fill Hydrophobic Down w/ sewn-through insulated bottom)
  • Reflective ThermaCapture lining for added warmth without excess weight or bulk.
  • ToeAsis Foot warmer Pocket
  • SynergyLink Connectors integrate your mattress for optimal comfort and efficiency
  • Heat trapping draft collar and full-length zipper draft tube
  • Women’s-specific differential cut maximizes loft.
  • Snag-free zipper
  • Cinchable hood
  • External zip pocket
  • Stuffsack and storage sack included

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