    A synthetic mummy bag you can count on.

    Variable shoulder-season weather requires a reliable sleeping bag that can handle it all. Unroll the Marmot Trestles 15 Sleeping Bag after a long, cold day pounding the soggy trails. SpiraLoft synthetic insulation isn't threatened by wet weather and feels extra-lofty in comparison to your older synthetic sleeper.
    • 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 add weight
    • Easy to reach drawcords make adjustments easy 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
    • Item #MAR2274

    Pretty good deal for a great product.

    • Familiarity:I've used it several times

    I really wanted to try camping out and/or even backpacking in winter but wasn't sure which bag to get. So I searched until I found this Trestles 15 degrees on sale. I used it twice last January. First time I was in my boxer brief, felt warm no problem. Second time, I tried it overnight up 7,600 ft with snow and it did well. Only one thing that made it hard for me was that it used a lot of space inside my backpack. But for a short distance backpacking or car camping, I would recommend it. May not be the best but it won't hurt your wallet.

    You just gotta do it.

    • Familiarity:I've used it several times

    This is a fantastic sleeping bag for the price. I just used mine for some winter camping in Grand Teton National Park on a snowboard trip to Jackson Hole. For a synthetic bag, it packs down fairly well thanks to the stuff sack that Marmot includes with it. With a synthetic bag you don't have to worry as much about keeping it dry, because the bag will stay warm unlike a down-filed bag. Throw in a sleeping bag liner for additional warmth (usually about 10 degrees extra). I really like that it has a 1/4 zip on one side of the bag for nights where you don't have to be mummified. I am about 5"11 170lbs and the Regular is the perfect size.

    Cocoon of Comfy.

    • Familiarity:I've used it several times

    Judas H. Priest if this lil mummy love of mine ain't the sweetest sleep I've had hiking...EVER. It only got down to around freezing on the AT last week(hiked around 40 miles, 3 nights), but I just have a feeling this Marmot of joy is going to be just fine at 15 degrees or if I happen to sleep in a Wampa's ice cave (Star Wars, look it up)! Moses H. Cone, I love this thing!

    I'm 5'10", 174 lbs and I'm in love with a Marmot.


    Great bag

    • Familiarity:I've used it several times

    I love this bag. I stand 6' so I ordered the longer and wider bag. Not a fan of mummy bags, but this one, with the little bit of extra room allowed me to snuggle in AND could contain my clothes for the next day. I am always a happy camper in the early morning after sleeping in this bag. It definitely kept me warm, plus there is more room to add a liner or additional blanket if necessary.

    Surprisingly awesome!

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

    After freezing my buns off in an early spring camping trip, I decided to up my bag game for a fall trip to Vermont. I prepared myself to be cold, packed extra clothes and blankets, and even bought a box of hand warmers to put on my feet because I really wasn't sure how great this bag would be.

    Holy cow, it was great. SUPER warm within a minute or two of crawling in. I'd be shivering around the fire, run into the tent and into the bag immediately, and found myself toasty within minutes. Definitely recommend this to anyone on the fence, I'm thinking of picking a second up for my fiancé because she needs a new one, too.

    Cars, couches and camps

    • Familiarity:I've put it through the wringer

    This sleeping bag has seen me through all of my adventures for the last three years and I have never had a problem. I made it through some sub 10 degree nights, though it required extra layering inside the bag. It's been perfect for all of the 25+ nights though, nice and cozy. If it packed a bit smaller I wouldn't complain, but hey that's not the reason I bought it, I bought it for the cheap and bombproof bag it is. I am 6'2 and I ordered the long. It fits with a little extra room in top (or bottom).

    great functioning bag

      I havent bought a bag in 20 years and needed one for a 3 night presidential range hike. The price seemed too good to be true. My real concern was size. I'm 6'4" and a little claustaphobic in a mummy bag so i needed the long wide, but would it fit in a 5500" back pack? Answer is yes. Its a very snug fit, but worked out. The stuff sack is real key. Two nights were dry and in 40's. Toasty warm. Third day everything we carried got soaked thru. We forgot water proof plastic bags. Bag was wet but stayed fluffy and really got the job done with wind chills in the 30's. I think its great for short term backpacking. Just be sure of the size you choose and the pack its going into.

      Through Snow and Rain...

      • Familiarity:I've used it several times

      I've used this sleeping bag for about four trips. Two of those four trips were in Utah at Zion National Park for a race I was running. The first year, it snowed. The second year, it was a monsoon. Both times, this bag wrapped me up, protected me, and kept me safe and warm. I will now officially ask it to be my maid of honor at my future wedding.

      Wedding plans aside, seriously, this sleeping bag is awesome. It has kept me beyond warm in temperatures in the 20's (I have yet to get a really cold night in there) and it's very comfortable and functional. I'm 5'5" and I haven't had any issues with awkward bunching or the zipper not working because of extra slack. It's really easy to clean and it stuffs down fairly well. I see this bag in my future for a while!

      saves wallet and butt

      • Familiarity:I've put it through the wringer

      Bought this for winter hiking in the southern portion of the AT on my thru-hike. When it got down to the teens and single digits at night I would cinch it up to block out the draft and wear my down jacket to keep me just warm enough. This bag saved my hike! It WILL snag if you don't keep the fabric taut as you zip.

      Perfectly pleased

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

      I was looking for a solid bag to replace the old super heavy one that I own. I didn't want to spend too much money either. This bag satisfied everything I needed and wanted and more. I've used it a couple times and have never slept so warm in my life. (I have bad circulation to my feet so they are always cold, but every time I've used this I've not had any problems). Not super light so won't be perfect for extensive packing trips, but definitely my go to bag for the overnighters and traveling from now on.

      I really like the material and feel of the bag. I was a little nervous with purchasing Marmot as some people have had issues with tearing, but this one feels like it will last. I also really like how they have glow in the dark tabs on the zippers, so much easier than fumbling around for it.

      I'm 6' even and the regular size fits me with plenty of room to spare, so the bag is plenty large enough and doesn't run small.

      Just wish we'd get some snow so I can go snowcaveing...

      Great for spring and fall...

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

      I've only gotten to use this bag once, but I was impressed with it nonetheless. I took it out and temps got down to below freezing and I stayed cozy in my tent throughout the night, but I also wore baselayers while sleeping. The bag comes with a stuff sack that has compression straps on it, but doesn't compress well. It is sythetic so that is expected. I would recommend this for beginner or novice hikers that don't mind bulkiness and extra weight. Not for hikers who are looking to go light, but for the price it's a great bargain and well made.

      best sleeping bag i've bought

      • Familiarity:I've put it through the wringer

      The photo above shows the length of the bag against my two person Kelty tent. Fits nicely inside.

      I lived out of my car for three months in Jackson Hole to puruse all things nature has to offer as cheap as possible and used this as my covers/bed. It was fantastic. One morning I woke up and realized I had kicked over my toothpaste and it squirted all over the sleeping bag in the middle of the night I washed it and it was good to go. No rips, no tears, no damage after using it every single night for three months not to mention taking it on various camping trips. Very warm. When I had it zipped up all the way I never had issues getting cold.

      best sleeping bag i've bought

      Thumbs up.

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

      Used the bag in upper 20's and low 30's without a sleeping pad, was still very warm and comfortable. It packs a little big, but I had no problem fitting everything needed in my pack. I'm 145 at 5'7" and purchased the regular size - it was perfect, some room to spare.

      Love it

        Sleeps great, have used in warmer temps and have been fine. Cleans up well. Wish it would roll up smaller but that might be me. Also the zippers catch and have torn fabric on 2nd use, bummer. But overall I love the bag. Have one for myself and oldest son.

        Awesome bag

        • Familiarity:I've used it several times

        I've used this bag quite a few times and I love it. I've taken it down to -10c and stayed perfectly toasty and warm, even in a hammock. I would recommend this hammock to anyone looking for a solid sleeping situation

        Zip-together compatible!

        • Familiarity:I've used it several times

        First of all, this bag is super comfy and warm. It's not TOO skinny that it's constricting, and it's not TOO wide that it's breezy. I'm 6'1, 180 pounds, and the Long XL-Wide seriously hits the money spot on size for me. I got the long wide, and my wife (like, 5'5) got the regular size- and they zip together just right- as long as you get one right zip and one left zip. Another nice feature if you're planning on zipping together these bags (even if you're not, for that matter)- is that each bag has about a foot and a half long zip down the opposite side of the main zipper- which is nice for temperature regulation. muy bueno!

        Snug Bugs in Warm Rugs!

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

        This is one toasty bag. I wanted it for a backpacking trip to Iceland and the weather would be in the low 30s with a wind chill. The warm factor was there for sure but the size and weight factors just weren't there. For a synthetic bag its not too bad but for size in a compression sack.. but for a backpacking pack that I was hoping to keep around 30 Lbs it just wasn't practical. I ended up going with a down bag with a 15 degree rating by Mountain Hardware that I was really happy with. So when it comes down to it I would go with this bag for warmth but not for size/weight.

        Great Bag

        • Familiarity:I've used it several times

        Took this sleeping bag to Moab and then to Ibex the next weekend recently and it performed incredibly well for both places. The temperatures in both areas were about 40 degrees F, so I actually had to unzip the bag during the night, but I'd much rather be too hot than too cold. The bag fits my wide shoulders very easily and is incredibly comfortable, I strongly recommend this bag for Spring, Fall, and Summer adventures.

        how well does this compact down? I'm looking for something that takes up minimal space in my bag.

        I'm 6 feet tall, so right on the border for the regular size, what length of bag would you recommend? The regular or the long?

        How big is the long sleeping bag when compressed in the stuff sack?

        Does any one know if you can zip together the long version with the regular size version? I'm 6'4" and my wife is 5'2"

        Does this compress well. I want to fit it into the backpack sleeping bag area at the bottom of my pack with no issues. Thanks NES

        Synthetic insulation will never compress as well as down but this sleeping bag is very skinny(mummy)so it will pack small. You will not have any issues getting this bag into a sleeping bag compartment but if you want to compress as much as possible check out some compression sacks.

        I love Marmot products. I have been going back and forth between whether or not to purchase this bag or the North face Women's Aleutian. I like how this is rated warmer and seems to have solid reviews but the Aleutian has a tad more wiggle room. I'm 5'9" and 125 pounds so i know I need a long but has anyone felt too confined in it? Otherwise, it seems to be a superior bag and offers a bit more warmth and water-resistance. I'm also more of a spring to early fall camper so not hardcore winter temps person. Any input would help! thanks

        Does this bag come with a storage bag and a stuff sack?

        Since this bag is a synthetic insulated bag and compression does not negatively affect the integrity as it would to a down bag this bag does not come with a storage bag. I would still suggest storing your sleeping bag out of the stuff sack anyway. I keep mine on a hanger in the back of the closet so that there isn't any issues with mildew.

        I need a 3 season bag that stuffs small

        Best Answer

        This is a synthetic bag and won't compress as small as a down bag. Search for a down bag, preferably 800 fill. If 800 fill is out of your price range, 600 is still great and more affordable.

        For a 3 season bag, I recommend a 30 degree bag, unless you plan on some high altitude backpacking that may drop below freezing.

        This bag comes in a pretty good compression sack, you can squeeze it down pretty small. I've never had any trouble getting this into the sleeping bag compartment of my pack. As for the previous response, if you're anything like me I'd stick with a 15 degree bag. Im a cold sleeper and this bag keeps me comfy down to about 25 - 30 degrees much colder than that and I'm chilled. And, if you're sleeping in warmer temps mid summer its easy to un-zip and let a little air in. Good all around bag, especially for the price.

        I'm 6'2" and 175 lbs. I tend to like a little bit of wiggle room and can get claustrophobic. Is the x-wide too big? Anybody have any thoughts? Thanks!

        I am about about 6 foot and a half inch tall 188 pounds. Would someone this size usually prefer the regular or the long?



        Best Answer

        I'm the same height as you... but much much skinnier (135 lbs.) I always a buy a long sleeping bag. Yes, you could fit into a regular and cut some weight but then you'd be compressing the loft towards the feet and would be quite cold (you need the loft for warmth!). Also, I doubt you sleep with your feet pointing straight up, which is also another reason to buy the long.

        Can you zip two trestle bags together?

        Can you zip two trestle bags together?

        It's easier to zip two of the same EXACT bag together though. Seems obvious, but whatever. I have the Trestles womens and zip it to my boyfriend's Trestles and the zipper on his is a little longer, which is a pain sometimes to get apart to re-pack them.
