Idaho's got nothin' on Marmots.

The Marmot Sawtooth 15 Degree Down Sleeping Bag weighs under three pounds—that's less than 16oz for each of the three seasons you'll be camping in. Compact, lightweight, and insulated by lofty 650-fill down insulation (treated with Down Defender to keep it warm if it gets damp), the Sawtooth helps you slumber soundly spring through fall, and even on mild winter hut trips. A host of features like a down-filled collar, five-baffle hood, roomy, trapezoidal footbox, and draft-stopping zipper tube add to the light-and-warm comfort.

The Sawtooth features a mummy shape that offers plenty of room at the shoulders before tapering down at the feet to keep insulation closer to your toes, which are going to be extra-warm thanks to the heat-trapping trapezoidal footbox. It's been designed with stretchy baffles to accommodate your inevitable nighttime thrashing, and a face muff to seal the warm air in around your mug. There's even a stash pocket to keep nighttime items close by, and hang loops for easy drying and re-lofting.

Unanswered Question

I am a 5'11", 150 lb, athletic-build female. I want to purchase this bag because I can't find a women's equivalent I like enough. Any advice on whether this bag (in reg length) is a good unisex bag? I don't have particularly wide hips.

What size stuff sack should I use for this sleeping bag?

I have the preprepredecessor and it fits nicely into a Mammut M.

Does anyone know what makes this 15* bag different than say the 30* Never Winter bag if they both have 650-fill down?

Hey ChucktheSkipper,

The Marmot Sawtooth has a greater amount of 650-fill down (ie higher fill weight) than the Never Winter 30-Degree Bag which makes it warmer. Also, the Sawtooth is about 8 ounces heavier in the regular size compared to the Never Winter as a result. I have the Sawtooth and it is one of my favorite pieces of gear so feel free to shoot me any other questions directly,

Not Bad....But

  • Gender:Male
  • Familiarity:I've used it several times

Ok, I am going to get down on the bag a little but stay with me. I would have rated it a 3 star but the help I got from Backcountry made me bring it up to a 4 star, so the extra star is not for the bag but for the customer service, Wanted a bag for summer and winter. Went on two hunting trips this year with this bag. First one was in August in California high country and I sleep very well. Nice and warm, but the temp. was only in the low 50s to high 40s at night. Second trip was in October same spot. This time it rained and temp went into the med to low 30s. Sleep with everything on, and my feet were freezing all night. On the second night I put wool socks over my reg. socks, put my feet inside a sweatshirt and even put a blanket over the bottom of my bag. This worked and kept me warm.
Called Backcountry and they were very helpful. They are letting me return the bag and I ordered a 0 deg. bag to replace it. I paid a bit more and I am hoping it will be worth it. They also told me that they had gotten another caller earlier today from someone that was having the same cold feet problem I was having. They said there might be a problem with the bag and they would be looking into it.
When I get my new bag I'll do a review for it also to let you know how it works out. It's a Kelty Ignite 0 deg. (item #KEL0864).
I think Backcountry went out of their way to work with me to make things right. I will be sleeping in the new bag as soon as it gets here so I'll know right-a-way how it works in cold weather. I got to be warm or it's not worth what ever I paid for it.


Marmot Sawtooth 15 Degree Down Sleeping

    Order and received the afternoon before leaving on a backpacking adventure in the mountains. This bag was an absolute wonderful purchase! The nights would be in the mid-20's and I was completely warm, sleeping all through the nights! Zipper hangs up some, but wasn't a really big deal. I've owned several backs in my lifetime and they all have gotten hung up


    Best bag for a modest price!

    • Familiarity:I've used it several times

    First, allow me to stress how wonderful I think this bag is. It compacts down very well, which I something I found very important. It's not very heavy either, it only weighs about 3 pounds. Though, what I was really impressed with was how warm it kept me. A few friends and I had to camp out at 13,000 feet in an all out blizzard and I was hardly cold. The bottom of my bag was soaked too, but the bag kept me completely warm. Marmot makes really great products, so I encourage you to buy this sleeping bag if you’re looking for a great 3-season bed.

    What is the claimed weight for the long sized bag? I long see listed the regular size at 2lb 11 oz

    Hey Greg,

    Looks like we appreciate the same gear! I have the Marmot Sawtooth Bag in Long and it weighs approximately 2 lbs. 14 oz. Feel free to contact me if you are interested in placing an order for this sleeping bag and the Zeus Down Jacket.

    Great Backpacking Sleeping Bag

    • Familiarity:I've put it through the wringer

    Lightweight, warm and a compresses down to a small package!


    it does what it says it does

    • Familiarity:I've put it through the wringer

    I've owned this for 2 years now and have been all over the place with it from spring camping in Sonoma County to winter high deserts below 14. This is a standard 15 rating and though I run hot when I sleep, I would say 15 degrees out is still close to comfort. I often sleep with just my underwear and that seems to work best especially if it's not actually that cold. Anytime it's not below 40 there is a constant shuffle between the inside and outside of the bag. I don't mind, but it can get too hot. (I was glad I didn't go for the 0 degree bag). The comfort ratings had really spooked me when I was first shopping.

    I'm 5'3 and there is plenty of room at my feet, I especially like it to keep my morning clothes dry from dew/frost and it helps retain heat. (I also often sleep with out a tent and we've forgotten our tarp plenty) The water resistant layer has kept me warm and dry despite heavy dew/frost which goes through my partner's 0 degree and bummer he's cold :( .

    Sometimes it will loose feathers but it's kept it's contents super solid. My partner does his best to make sure our bags are the first things to get set up so it's rarely compressed for too long. It does however pack down real nice and regain composure within the half hour.

    It does has neat features, like the stash pocket, honestly the only few times I've used it, I forgot by morning and thought I lost my keys and the other time my headlamp/ rolling onto them is also a real discomfort. Though I really like the glow in the dark zipper handles.

    I'm glad I got it, it's quality gear and does exactly what it's supposed to do.


    It's warm dude

    • Familiarity:I've used it several times

    I climb in the southeast. Camping around the crags I've been cold my fair share of times. No more. If you're not an ounce freak this will work for all your backpacking and camping needs. I'm surprised every time it fits into the little sack it comes with. It is so warm, I was sweating using it in the low 30s with only a t shirt and my skivvies.


    Perfect for my needs

    • Gender:Male
    • Familiarity:I've used it once or twice and have initial impressions

    I wanted a lightweight bag for my 14 year old son who has been backpacking since he was 10. We took it on a 4 day trip in the Tahoe National Forest this August. The nights got down into the 40's and Rob reported he slept well, if not a bit hot. He used a EXped Downmat UL 7 as a pad which really help eliminate cold spots between the bag and ground. There is no compression sac with the bag but we really didn't need one. The stuff sac that came with the sleeping bag was small enough that the bag packed in the sleeping bag compartment of his pack with room for the pad. The zipper functioned well and if it got hung up, a simple tug in the opposite direction fixed the issue. Robbie really liked the draft tube around the shoulders as it made a sug fit without being too tight.

    I want to call out the customer service folks at for excellent service. We had a shipping mixup and they took care of it immediately, no questions asked. First class customer service!

    My bed spot under the stars at Lake Powell

    Please tell me you use a foam mat or a nice comfortable air mat under that nice sleeping bag.

    Well i am a silly gal, and free sort of spirit, sand sprite even! The sand contours my body well enough :P I will use a pad if i need it on some more unforgiving grounds.

    Pads aren't just for comfort...they're for heat transfer too...they keep you warmer, which I would think would be on your mind with a 15* bag.

    You are right about the warmth factor. However, I was not afeared at Lake Powell this summer!

    I just noticed it said Lake Powell...I spent 7 years in PHX...


    My New Fav bed!

    • Familiarity:I've used it several times

    I had been on the hunt for a durable, lightweight down for some time. All the women specific bags were heavier than id like, and I was on my last nerve! Then I found the sawtooth. It's construction makes it a go anywhere type of bag. The material on the bottom is tough, so you can put it right on the ground. The Down Defender makes it resistant to water so it takes some of the fear out of getting wet. I have slept in the mountains at under 15 degrees in it, and in the desert where i imagine it was 50. I am in love with my new bag!


    Comfy and light.

    • Familiarity:I've used it once or twice and have initial impressions

    This bag is super comfy. I like the hood because it makes me feel like I'm in a cocoon. Despite the bag being super light, it is still super warm. The fabric is high quality and is soft.
