DESCRIPTION
The Atlas LoftTek™ Hybrid sleeping bag is the most ultralight advanced synthetic sleeping bag in the world. The hybrid insulation allows you to handle the 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!
