About this item

  • ►REAL WARMTH: Atlas sleeping bags are real world tested to be warm within 5F of their rated temperature, making it warmer than industry standard “lower comfort ratings” and a more true temp rating!
  • ►FIRST OF IT’S KIND INSULATION: For year’s outdoor lovers have wanted the benefits of down insulation (lightweight, warm, compressible) without the downsides of down (fails when wet). Our new LoftTek Hybrid insulation utilizes cutting edge science to give you the benefits of down, without the downsides!
  • ►ULTRALIGHT WEIGHT: 650+ fill power LoftTek Hybrid insulation fills the bag, which gives you best in class weight to warm ratios being a mainly synthetic insulation. We wrap the hybrid insulation in a baffled (not sewn threw) lightweight ripstop shell to complete the ultralight sleeping bag!
  • ►PACK LESS: Not only does LoftTek Hybrid insulation have the highest weight to warmth ratio in its class, but it also is highly compressible! With the FREE compression bag we include, easily compress your sleeping bag to fit in any pack or space without needing to buy it separate!
  • ►WATER RESISTANT PROTECTION: Mixing 80% LoftTek with 20% 800+ fill power down creates a synergy allowing the benefits of down, but the moisture advantages of synthetic. Water simply drains out of the bag while staying completely warm and lofted! DWR coatings on the shell prevent water from entering in the first place!
  • ►LIFETIME WARRANTY: We work hard test our gear through torture tests and only use top quality partners ranging from certified down, top shelf fabrics and highly proven sewers! All this leads to us having the confidence to provide a lifetime warranty on your purchase. If there is a craftsmanship problem, we'll fix it!
