• Lofty SpiraFil insulation combines hollow fibers and denser, solid synthetic fibers in order to offer a balance of warmth, softness and compressibility
  • Insulation fibers are thermally bonded so the insulation maintains its loft and shape longer, meaning more warmth and a better performing bag in the long run
  • DWR-coated shell material fends off light rain and moisture so your bag and insulation stay drier in inclement weather
  • Snagless draft tube won't leave you trapped when nature calls in the middle of the night
  • Snag-free draft tube seals in extra warmth
  • Two-way zipper sliders enhance convenience
  • Included compression stuff sack helps save space in your pack
