  • Antares™ sleeping bag is insulated with quality 750-fill-power goose down for warmth, light weight and compressibility; zoned insulation puts down where you need it most
  • Fill is concentrated in the top for greatest insulation and used sparingly on edges and bottom where it's less effective; air pad required to complete system (included)
  • With a lower-limit European Norm (EN) rating of 23°F, the Antares is a versatile bag for lightweight spring, summer and fall adventures in the mountains
  • Bag is designed with extra space in the torso to allow for natural movement without restriction; bag tapers at head and foot for thermal efficiency, keeping head and feet warm
  • Ripstop nylon shell fabric feels nice and is lightweight, durable, water- and abrasion-resistant; nylon lining is soft and tear resistant
  • Includes full draft collar, adjustable hood, snag-free zipper and a stash pocket
  • Flexible fabric bands on the bottom attach the bag to the NeoAir All-Season sleeping pad, keeping you from sliding off the pad; bands accommodate pads up to 25 in. wide
  • Included NeoAir™ All-Season sleeping pad weighs only 1 lb. 3 oz. (regular length) yet provides 2.5 in. of cushion to keep you comfortable on the hard ground
  • R-value equals 4.9; most sleeping pads we sell range in R-value from 1.0 (minimally insulated) to 9.5 (well insulated)
  • The Therm-a-Rest Antares sleeping bag includes a stuff sack and storage bag; Therm-a-Rest NeoAir All-Season sleeping pad includes a stuff sack that doubles as a pump
  • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags
