Just-right insulation for three-season camping.

Even if you sleep cold through mild spring and fall weather, the lofty SpiraFil synthetic insulation inside the Marmot Women's Trestles 15 Sleeping Bag will surround your chilly bones and draw you into a comfortable slumber. From the toasty warm Nautilus hood (which shares its construction with that of Marmot's expedition-worthy 8000m jacket) to the roomy trapezoidal footbox, this bag was designed for fit and comfort over all else.

  • Women-specific cut and extra insulation in key areas help keep you comfortable at night
  • DWR-coated shell material fends off light rain and moisture so your bag and insulation stay drier in inclement weather
  • Lofty SpiraFil insulation combines hollow fibers and denser, solid synthetic fibers in order to offer a balance of warmth, softness, and compressibility
  • Nautilus Hood shares the same construction as Marmot's expedition-worthy 8000m jacket so your head stays nice and toasty
  • Insulation fibers are thermally bonded so the insulation maintains its loft and shape longer, meaning more warmth and a better performing bag in the long run
  • An overlapping series of internal insulation shingles creates the Wave Construction, which allows for more efficient use of insulation so you stay warmer without additional insulation that would increase weight
  • Easy-to-reach drawcords make adjustments a cinch when you're bundled up
  • Trapezoidal footbox matches the shape of your feet: wider in the toe area and narrower in the heel so you have more foot room and warmer feet
  • Zipper garages cover up the two-way sliders from the elements so they operate smoothly every time

Nice and toasty

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

Took this bag down to the desert and I was definitely satisfied! Slept in mid 30s in a tank top and leggings, no problems at all with warmth. Even got slightly over-heated. Bag is a little bulky for backpacking, but it's perfect for car camping!

Weak stitching and bulky!

  • Familiarity: I've used it several times

I originally bought this on sale for backpacking in the PNW since synthetic down doesn't lose its heat while wet. Now I wish I would have spent the extra on a down bag.

My first complaint is that it is bulky, so if you are backpacking you'll want the extra space for other stuff. You can definitely make it work though.
My second complaint is that it isn't very warm. The lowest temperature I've slept with this bag is 30 degrees yet I am still freezing and I'll usually wake up due to the cold.
My last complaint is that the stitching on the seams are weak. I just used this bag for the fourth time car camping and the zipper got snagged. I attempted to un-snag it with barely any force and the seam just split!
Definitely front the extra bucks for a quality down bag. The sawtooth is worth the extra money in my opinion.

Toasty warm

  • Familiarity: I've used it several times

I used this sleeping bag on my journey to the Grand Tetons. Although it wasn't very ideal for backpacking, it was perfect for a nice warm nights sleep in 30 degree weather. I started out with chill feet, and by mid-night I was burning up. I'm naturally a cold person. I'm always cold, so I was rather pleased with how warm it kept me. I slept on top of a therm-a-rest pro lite pad, so that helped keep the chill from the ground at bay. No campfire was needed on my two nights in the Tetons in September. I highly recommend this. Again, it doesn't stuff well. It stays fairly bulky, even in its stuff sack. It's worth it if you have the space.

Does this bag have a pocket for your sleeping pad to slip in to? I am debating between the Marmot Trestles or The Kelty Mistral Sleeping Bag: 20 Degree Synthetic.

Responded on

This bag does not have a sleeping pad sleeve, unfortunately; however, it does have a "stash pocket" located on the chest region on the interior section (see second picture of partially unzipped bag of the bag.
Hope this helps.

Takes up too much room

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

I bought this since it was on sale but I regret it. I bought it to go on a backpacking trip, which was why I regret it. If I bought this to go car camping I'd be extremely happy with it. I used it on a summer night in a hammock (with a sleeping pad under me in the hammock) and it did the job. I was warm enough through the night. My friend has the mens version and he had no sleeping pad in the hammock with him and he was cold (but he was warm sleeping on the ground with it just a week before). This sleeping bag is fantastic if you want it for car camping. For backpacking, it took up way too much room.

Long story short, I'll continue to use this sleeping bag for camping trips, but for backpacking I think I'll have to spend a bit more money and get another bag that packs down to a decent size.

Responded on

I completely agree! It is WAY to heavy & big for backpacking, but for car camping it is perfect! If you're looking for a backpacking sleeping bag, dump the money on a down bag; you will not regret it.

Unanswered Question

I love Marmot jackets and boots so I am...

I love Marmot jackets and boots so I am leaning towards this bag versus the North face Aleutian but that bag has a tad more wiggle room. This is also rated for lower temps and seems most women don't find it confining. I'm 5'8" and 125 pounds so I think it should be a good fit. Any one have any comparisons?

Excellent "Car-Camping" Bag

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

I was looking for an affordable, warm synthetic bag for my wife to use the 4 times a year or so we camp together as a family in the cooler months. At first I was going to get the 30-degree version, but reviews elsewhere made it clear that even in the high-30's, the bag was reaching its limit. I went with the 15-degree version of the bag and I'm very glad I did. The temps hit about 37 the first time she used it and she was perfectly warm, but admitted her feet felt a touch cool - but not cold. She's always cold, so it's clear the choice to go with the bag rated for the cooler temp was the right move.

In terms of fit, the bag was great. Not claustrophobic and plenty of room to turn and get comfy. She's about 5'10" and the long fit her perfect. Now, this of course means it's going to be a bigger bag. It's on the heavier side and pretty large - compressed or not. If you're car camping or only a short hike in... no big deal... But, I personally feel it's a bit too bulky for a significant hike in or a multi-day. I knew this going in though, so this bag performed perfectly for the need. I've included a picture of the bag uncompressed next to my Cloudbreak for comparison.

As expected, build quality is great and she never seemed to have issues with the zipper snagging or anything either.

If you're looking for a solid "car-camping" bag that can handle the cooler months without breaking the bank - this bag is a really solid choice.

Great bag

  • Familiarity: I've used it several times

After a year of trial my wife is really happy with her bag. It worked well in the summer with the extra 1/2 side zip open and through the fall it's kept her warm even when damp... We'll use it down into the 30s but she likes to sleep warm so layers up well at those temps

How small does the bag compress down? Is it appropriate for cycle touring if I put it on a rear rack?

Responded on

Hi Michelle,
The stuff size for this bag is 18 by 8.5 inches (compression sack included). You could definitely make that work for cycle touring on the rear rack.

Great Sleeping Bag

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

This bag is warm and durable. Packs down pretty small as well

Good value.

For the price of this bag, it's pretty good. I've always been a cold sleeper and have only been cold in this bag a few times, mostly during the late fall or early spring. I got it partly to zip together with my boyfriend's Trestles which is a great way to use it. However, the zipper on the women's bag is shorter than the men's, which is a pain when you're trying to get them apart to re-pack them. That's my only complaint; I'd recommend this bag.

Warm & Super Comfy

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

This is a GREAT bag. I use any excuse to sleep in it. It's really comfy. Zips up so far you could just have your nose and mouth poking out. And zips down on both sides if you don't want to feel trapped in it ;) I love that on warm nights I can just unzip at the bottom letting some air in for my feet or to poke a foot out. And the stash pocket is the perfect place for my phone or electronics to be accessed easily and quickly. It's also pretty light and compact for a 15 degree bag at this price and fits nicely in my backpack. Highly recommended for any lady wanting to be comfy and warm in the wild!

Perfect sized women's 3 season bag!

I am 5'6" and this bag fits perfectly. I just received it and am impressed by the excellent fit, the quality zippers, and the color. I am happy to report that the zipper and the Marmot logo are in a deep fuchsia color that compliments the two shades of blue on the bag very nicely. There is enough room in the bag to move around a bit, so it does not incite feelings of claustrophobia like some bags can. I am very impressed, and will leave additional info once I have put it to more use!

This bag is the bomb diggity

Regulates body temperature very well - perfect for a fall trip w/ nights in the 50s and lower. I am 5'8" and got the women's left zip/long so that it can mate with my boyfriend's bag. Backcountry's price was the best around - shipped very quickly, too!

Can I store this bag in a large pillow case and hang it in the closet.

Responded on

Sure can. It's a good idea to store it as you described; prolongs the life of the insulation if you don't store it compressed.
