NEW Atlas Hybrid 0- 15 - 30°F LoftTek™ Hybrid Sleeping Bags

NEW INSULATION - LOFTTEK™ HYBRID: The most advanced, ultralight & packable synthetic in the world! 0F models out of stock until November. 

  • 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! This means you'll sleep warm and comfortably even if your gear gets wet on your adventures!
  • ULTRALIGHT WEIGHT: 650+ fill power LoftTek Hybrid insulation fills the bag, which gives you best in class weight to warm ratios being mainly synthetic insulation. We wrap the hybrid insulation in a baffled (not sewn threw) lightweight ripstop shell to complete the ultralight sleeping bag! As a result, you don't have to sacrifice pack weight to stay comfortable and confident in your gear!
  • 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 separately!
  • 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!

The Atlas LoftTek™ Hybrid sleeping bag is the most ultralight advanced synthetic sleeping bag in the world. The hybrid insulation allows you to handle moisture of all kinds without failure and have complete confidence in your gear's reliability!

This is all made possible by our LoftTek™ insulation that looks, acts and feels like down, but has a siliconized coating causing water to drain out of the insulation. This in conjunction with 800+ FP hydrophobic coated down creates a state of the art synergy balancing insulation stability and moisture resistance! We put this insulation into a jacket and raised almost a million dollars in pre-sales, so we decided to put it into our sleeping bags as well!

Whether you like the confidence of synthetic, face extreme moisture down insulation can't handle, or simply like the price tag of the Atlas LoftTek™ Hybrid bag, you won't regret it!

Product Features

  • A combined fill power of 650+ that will keep you warm and your pack light so you can more fully focus on your adventures! 
  • Utilizes 80% LoftTek synthetic loose-fill insulation with 20% DWR treated 800+ fill power down to make the most advanced synthetic in the world! This means you will stay warm with fully lofted insulation even if your sleeping bag gets wet!
  • Dries quickly if somehow damp, so not only will you be warm after a situation with moisture, but you'll soon be dry again as well!
  • Compresses to small sizes like traditional down bags so you can have space for the rest of your gear, which will allow you to enjoy timeless moments without worrying if you brought everything you need!
