Helium Sleeping Bag: 15F Down

Why We Like The Marmot Helium Sleeping Bag
The Marmot Helium Sleeping Bag dials up the warmth while dialing down the weight, thanks to its use of premium materials. That starts with 800-fill goose down that's been treated with Down Defender to make it more weather resistant and to protect its loft for long-term insulation. We also like the Pertex Quantum fabric for a light but rip-resistant finish that helps keep the Helium's weight hovering around two pounds. The mummy shape also sheds a few grams while holding in more heat, along with the insulated draft tube and Nautilus Multi-Baffle Hood. This bag packs down small and doesn't weigh us down when we're backpacking or mountaineering.

Excellent night of sleep
[This review was collected as part of a promotion.] Soft as butter, toasty warm, light as a feather. This is a go to back for cold backcountry.

Very light and very warm!
[This review was collected as part of a promotion.] Purchased this bag for shoulder season backpacking in Colorado. I used it for the firsttime last weekend. Night time temps got down to around 28F and this bag kept me toasty and feeling warm all through the night. It is incredibly light weight considering the fill and has a nice feel to the material. The only thing I would change is to have the secondary foot zipper extend further into the foot box area. It doesn't expel heat fast enough if you run warm.

I see this bag comes with a stuff sack. When backpacking can I and would it harm the bag in anyway if I put it in a compression bag and can you tell me how small it will compress?

Hi there! Could you describe the difference between this Helium 15 and the previous (monotone) model? Is this bag also filled/finished in USA?
