Marmot Helium 15 Degree Down Sleeping Bag Regular

I purchased this bag to replace a Western Mountaineering Ultralite. I liked the WM a lot but the hood design was not to my liking. I have several Marmot products and wanted to give this one a shot.

The bag is much roomier than other lightweight bags of this temp rating. It will stuff down very well, but puffs up like it is on...well...Helium.

Marmot has the best hood and footbox designs in the industry in my opinion.

I've had it down into the single digits and low teens, as recently as this weekend we were in 18 degree temps and I had on a hat and toplayer only...my face was cold but I was very warm in the bag.

This bag will never let you down...It ain't cheap but at 3 a.m. when your optimistically rated bag lets you down $100-200 extra, (I got mine 35% off) will not seem like a lot of money

Haven't had it long enough to know all the pros and all the cons, but we took it out or an overnighter this past weekend where night-time temps dipped into the low 30's, and it kept all covered areas snug and warm (without having to be zipped up!). Using for 3-season camping. I confess this was a gift for my husband whose body-temp tends to always greatly surpass my own. If I were buying for myself I would have gotten a 0-degree bag, but I believe this will suit the combo of his body temp and the outdoor temps we dare to encounter early springs and late falls.

Happy thus far! :)

A very nice sleeping bag. Lightweight and lofty! Packs down very small, with or without the stuff sack. Have only used it once outdoors so far, and was comfortable down to about 25 degrees, with my breath frosting on the outside of the bag -- haven't tried colder. (I've also slept indoors in it, for fun, because I'm fond of it.) Nice room by your feet to keep morning clothes warm. Cinch around the head seems to do a good job. I can't comment on long-term durability yet, but it looks and feels quality.

I have had a Marmot Sawtooth sleeping bag for years which I used for 2 - 7 day backpack trips in the High Sierras. I have been trying to cut down on my wieght and this new Marmot Helium sleeping bag does just that without reduction in comfort or warmth. It is well worth the money in my book.

If you can only have one sleeping bag, the Marmot Helium is it. I use it for car camping and backpacking as well as a down comforter at home during winter months. On warmer nights, I just unzip the zipper and sleep with one leg out and one leg in.

This bag is an excellent 3 to 4 season bag. At 15 degrees its pretty close to its actual rating and can be used across many different temperature ranges, seasons, elevations, latitudes. Its usually warm enough to get through winter camping but its too warm for most summer uses.

Very comfortable bag, zips up and open easily and the bag "creeps" on the pad much less than other bags I've used. The lining fabric seems to be less clingy so turning in the bag is easier - the whole bag doesn't go with you.

Going to test this bag out in Sept. A friend recommended for comfort, warmth, and carrying weight. I was impressed with his Marmot last yr.

Used bag on a 6 day trip in the Sierra Nevada Mountians in September. Bag was lightweight, warm and comfortable.

Use this sleeping bag while thru hiking the CDT in 2010. I was always warm and comfortable.
