    Quality warmth at an affordable price.

    Break out the Marmot Trestles 15 Sleeping Bag after a long, cold day of pounding trails and enjoy a cozy, uninterrupted night's slumber. The resilient 70D polyester fabric that makes up this bag's shell holds up against seasons of abuse, while its DWR-treatment helps shed moisture if a light rainstorm briefly passes through camp. Lofty SpiraFil 120 insulation combines hollow fibers and denser, solid synthetic fibers in order to create a balance of warmth, softness, and compressibility. This type of insulation innovation ensures you're sawing logs comfortably in temps as low as 15 degrees Fahrenheit.

    The Wave Construction, which implements an overlapping series of internal insulation shingles, creates a more efficient use of insulation to keep you warmer without adding bulky, unnecessary weight. The 3D hood fully encompasses your melon in toasty comfort and protection from the cold, while an insulated collar and snagless draft tube seal out chilly winds that come along with cold-weather camping. The trapezoidal footbox is wider in the toe area and narrower in the heel so you have more foot room and warmer feet, and zipper garages cover up the two-way sliders from the elements to ensure they operate smoothly for years to come.

    Warm and Big

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

    I have used this sleeping bag a couple of times now and it has made my camping experience much more enjoyable. It is warm and the best part is, it is long enough. I am 6'1" and the extra length is perfect for me. This sleeping bag has all I need for car camping and short hikes to a camp site. Love it!

    Great Bag for the Money.

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

    I've only tried it out once on a test run in the back of my property. The temp range that night was from 62 - 40f. I was plenty warm all night. I purchased the long / wide bag and it was nice and roomy. I am 6'1" 225 lbs for reference. I was told that this bag won't compress to as compact a size as a comparable down bag but it seems to be a great bag for the price.

    Great price, good value.

    • Familiarity: I've used it several times

    While its fairly heavy and definitely bulky, I've loved this bag for saving me on cold, wet nights outside and when forced into my car by storms. The chest cinch is great for keeping you warm, and for creating more warmth circulation if you want to scrunch down in the longer bag (I'm 5'8). You'll want something lighter and warmer for anything other than short trips or car camping.

    Great bag

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

    Took this on a winter backpacking trip. Easy to pack, kept me warn during the 15 degree night on top of snow. would buy again.

    Good for car camping

    • Familiarity: I've used it several times

    I ended up getting this bag right before I went on a week long car camping trip at the beginning of December to a few different parks in Utah and Northern Arizona. My gearhead Kyle gave me some really great recommendations for new bags (my old REI bag had a big rip and needed replacing) but I ended up wanting to be cheap and bought this instead (sorry Kyle!). I put a liner in it and was pretty warm. The only night I didn't was when it was full on snowing and the low was about 5 degrees, even then I was alright with just slightly chilly feet (I layered up). In Zion though I was perfectly fine and not cold at all (with the liner).

    Overall, this is a really solid bag that I used a ton on this trip and look forward to using for the rest of the year when I go car camping. I will likely need to get another bag for backpacking because this is rather bulky and heavy, but I definitely recommend it! Also- I am a 5'9 woman who got a regular. It was a little snugger than I'd like so if you're a little taller and broader I'd recommend a long, especially if you're only car camping.

    3 season basic bag

    • Familiarity: I've put it through the wringer

    I have used this bag for years now and it has help up nicely. I recommend using a liner with all bags to extend their life. I am 6'2 180 lbs and i wish i would have gone regular length and not long, to much extra room to try and keep warm. this is everything you need and will keep you warm down to temps in the low 20s

    3 season basic bag

    • Familiarity: I've put it through the wringer

    Used this bag mountain guiding in British Columbia Canada. Pair this bad boy with a bivvy and you have your own personal heater. Great bag for the price. Don't worry about the weight. As someone who has packed heavy as a guide and close to ultra light on my own I would say the weight thing is relative.

    Cold and heavy

    • Familiarity: I've put it through the wringer

    First off, most of the people in these reviews must have had a heater in their tent or are lying about the temperature. I took this into the Bob Marshall wilderness in September 2016. It got down to the mid to upper 20's. I was frozen in this bag. Not to mention it is incredibly heavy for the warmth rating. For comparison on warmth to weight - I have The North Face Inferno which is rated to -40 and weighs 4.25 ounces less. I tried to go cheap with this bag, and you get what you pay for.

    Great purchase.

      If you are looking for a warm bag to use for not a bad price and decent packability, look no further. I've used this bag in the mid 20s and stayed very warm. It is obviously a big bigger than expensive sleeping bags, but it's a great buy. Very satisfied with my purchase, I've used it in Zion, Big Bend, Grand Tetons, all during the winter season and have stayed very warm. And that is with no sleeping pad, and thermal underwear. Actually packs down pretty small , enough to fit in a backpack. I'm 6ft and the regular fits great.

      Great purchase.

      15 degree grade is NOT accurate

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

      It's a very comfortable bag, and the price is an obvious attraction. I was also impressed with many of the other reviews people had from using the Marmot Trestles 15 bag. I purchased the a Long bag. It was relatively large, and I really had to shove it down my pack to get it to fit.

      However, I would say that it really only keeps you warm down to about 40 degrees F. After hiking for 3 days on the Appalachian Trail, I had two different nights where one was about 40 F and the next high 20s. The second night I had on not one, but TWO layers (thermals and pants, sweatshirt and jacket, with a skull cap on). I wasn't freezing, but still felt very chilly for what I was wearing.

      Overall, it's still a decent bag, but I would NOT recommend taking on a trip where you're expecting it to drop below freezing during the night. 40 degrees F and above, and you'll be nice and warm.

      Hey Hendrik! Thanks for the feedback! Temperature ratings are wicked-tricky and depend on a variety of factors including the age, sex, height, and weight of the user, not to mention the sleeping pad it's coupled with. If you have some questions about finding a warmer bag, or adding a liner or different pad for this one, let me know!

      Great Bag!!!

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

      Used it for my first backpacking trip. Slept in a hammock over what was around a 37 degree night and was the only one out of the group that was warm. The worst part of the trip was having to get out of it in the am. My only complaint is it doesn't compress down small enough for the pack size I had but chalk that up to inexperience.

      Everything is great, but...

      • Familiarity: I've put it through the wringer

      Ive used this camping a lot in the past couple months up in the CO high country and I have almost only good things to say. It is light and stuffs easy, keeps you warm even when the temps dip near freezing. however the zipper catches every inch while you're zipping yourself up which is incredibly frustrating especially at 2am when trying to get back in and warm. I would recommend this bag because of the great price point and features but be aware that the zipper takes some playing with!


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

      For the price you really can't beat what this sleeping bag has to offer. I do wish it packed down smaller but it isn't too big considering the price.

      Great Overall Synthetic Bag

        This Sleeping Bag is great! Whether it is for a week long expedition or a car camping trip! It does great in the elements and packs up to a reasonable size for an extensive backpacking trip. Definitely recommended this to those who love backpacking on a budget!

        Definitely warm and cozy

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

        I have gone camping twice now with this sleeping bag. The first time was at Mount Diablo on a rainy and foggy weekend. I was pleased to find that I would be unexpectedly warm throughout the night. I am kind of a wuss when it comes to being cold so I still put an additional blanket on top just to make sure I am warm. But I have never slept so comfortably while camping. It is very soft, a little fluffy so there is some cushion between you and the ground, and easy to carry/store somewhere. I will see how it is in the hotter months for camping. Might be too warm. But I would prefer being too warm than too cold in these situations.

        Seems ok

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

        I have not really gotten to try this yet. Its only been used in my living room after purchasing. The only thing I dont like is the zipper seems a little tricky.

        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?

        Best Answer

        Always err on the long side. If it's too short, you'll compress the insulation in the end and your feet will get cold, but if it's too long, you can always wad up some long underwear down there and fill the dead space.

        MAR2274...I'm interested in purchasing 2 sleeping bags but would like to know if the two can be attached

        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.

        HEY ERICK,


        Hi Erik and Grant, I was told there is a difference for Men vs Women sleeping bags. A men's 15 degree bag equals a women's 5 degree bag. So if you purchase a women's 25 degree bag, it'll feel like you're in a men's 15 degree bag.

        I love Marmot products. I have been going...

        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.

        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 considering the long vs. the x-wide long.

        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.

        i agree with sam that you should buy the long. however, you'll have a little too much extra room by your feet and they may feel a little more cool than you would prefer. if you shove some extra clothing in the footbed, it should help.

        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.
