Serious warmth at a silly price.

When you're meandering through the wet and wild climate of New England, there's no knowing what Mother Nature will throw your way, so rely on the Marmot Trestles 0 Spirafil 0 Degree Sleeping Bag to assure unwavering protection and dependable warmth as you drift in to snooze land. Fortified with a tough polyester exterior and DWR treatment, the Trestles fends off light precipitation in the face of inclement weather, while the lofty Spirafil insulation provides lightweight warmth—even when wet.

Additionally, the Trestles features a fold-down secondary zipper that offers a comforter-inspired feel, and the insulated collar, paired with the snagless draft tube, provides warmth that's akin to sleeping in your own bed. The drawcords are within easy reach to make adjustments more amenable when you're bundled up. Not to mention, the trapezoidal foot box matches the shape of your feet, meaning that there's more room in the toe area and less in the heel—ultimately providing more overall room for your feet and assuring that your feet stay roasty-toasty warm.

  • A versatile sleeping bag for camping in inclement conditions
  • 0-degree rating is ideal for cold weather
  • Spirafil synthetic insulation stays warm when wet

Warm Bag

  • Familiarity: I've used it several times

Comfortable warm bag for my trip to Maine in the mid 20s. I bought this for car camping. 0 degree Probably not a bag for hiking in, a bit bulky, doable but bulky. Needs a bigger stuff sack. Typical issues with the zipper. Always gets stuck a little when you need to get out of for natures call. Zipper works fine when you take your time using it. Dual zippers are nice so you can use bag as more of comforter. I like the zippered pocket in the bag, keeps my cell battery warm and helps hold the charge. At 5'-10

Cozy Warm All Night

    Took this on a backpacking trip recently and was very glad I had it. The first night was ~30deg and everyone else woke up complaining about how cold they were but I was cozy and warm all night. Used this bag and a 15deg underquilt with my hammock and slept like a baby. My only complaint is that the bag is a tad bulky but not a deal breaker, especially considering the warmth it provides.

    So cozy and warm!

      this sleeping bag is the best thing that had happened to me in every cold night i was outdoors. I get so cold so fast, and every time i get into the bag im just happy and sure that i will get a nice sleep. The only reason why i didnt give a 5 star, is because it is pretty large and weights a lot...i wish it was lighter, then would be the perfect sleeping bag... but anyways, this bag is so good, confortable, cozy and keeps you so warm, that you will not mind carrying it... or at least that's how i felt in my trips!

      Toasty Warm

        I love this thing. I've taken it camping twice now, and both times it got very cold at night but I was very comfortable and warm. I love the drawcords, they are easy to adjust. I also like the little pocket up top, I keep chapstick and tissues in it so I have easy access to them in the night. Only thing that's bothered me this far is I am pretty sure the foot area is even more insulated, because my feet get insanely hot and I have to unzip from the top to let them breathe.

        Kept me warm

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

        I'm happy with this bag, Kept me warm with weather in the low 20's. The zipper did get stuck on day two of camping, which I was very difficult to fix.


        • Familiarity: I've used it several times

        Took this out to Bryce Canyon for a winter trip and was so thankful I went to a zero from my old 20 degree bag. Temps dropped to low single digits at night but I was just fine in this bag. So warm and comfortable! I didn't feel like I was squeezed into a tube and could easily roll onto my side and fall asleep every night. Reaching outside the bag to grab a drink of water or turn off my light was freezing but once I zipped back up I could instantly feel the heat warming me up. Definitely recommend this for car camping or if you have a pack mule, but is probably on the heavier side if you're backpacking. Favorite Spec: Draft Tube on the collar of the bag. So handy and could actually feel it trapping in the warmth.

        Warm Car Camping Bag

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

        Used this in Joshua Tree over Thanksgiving. Temperatures fell into the mid-20s and the bag kept me nice an toasty. It is a bit bulky, but I plan to only use it for car camping so not a big deal.

        Large but quite warm

          Great bag, however if you are a really light packer it may not be for you, I got the largest size and it is a bit difficult to fully stuff into the sack, but it sure makes up for it on those cold nights!

          Hefty, but cozy

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

          I just used this bag for some winter trekking/camping with the following conditions:

          - Lowest night time temperature of 14 F
          - Relative humidity of 90%
          - Forested camp location
          - Slept in base layer of marino wool
          - Used in combination with a Therm-a-Rest Traillite

          Whereas this bag was somewhat a pain to lug into the bush (it's big!)
          I was glad to have it. It was comfortable and warm, and I slept well. I felt I could have easily stayed comfortable if the temperature dropped a little further. If it was much colder, or if I had to carry it over large distances, I would consider other options. That being said, for the conditions stated above, this was an excellent product.

          Best Value Zero Degree Bag in the world

          • Familiarity: I've put it through the wringer

          I slept "okay" (not very warm, but not cold) in this bag at 9 degrees in a tent on a good pad (zero degrees would be pushing it, even with very warm clothing like thick wool socks and a down jacket). I agree with all the other positive things written in the many reviews below.

          As far as the weight, critics should realize that you don't get close to Zero Degrees without weight! And you have to spend 2X to 3X the cost of this bag to save just 2 pounds (see any other zero-degree bag on this website for proof of this). Does a measly 2 lbs make that much difference to anyone who's not a minimalist camper?

          The only serious issue is the space it takes up in your backpack--which IS significant--but not the extra weight. You cannot beat this value in any case.

          Weighted warmth...

          • Familiarity: I've used it several times

          Ok, the only reason I wouldn't give this bag a fifth star is that it weighs a ton. This is not the sleep sack to put in your back pack. It is the perfect sleeping bag for Camping in the snow or in the back of your truck on a "ski bumb" vacation. The bag has all the bells and whistles minus the 800 down. This bag is sold at a more than fair price, crazy not to have this bag in your outdoor arsenal.

          Toasty in the cold

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

          I loved this bag. It was comfortable, easy to use, packs well, and very warm. I used it in close to freezing weather, and I was very, very comfortable with a set of fairly thin long underwear and a hat. Shockingly, I had to take my socks off because my feet got too warm, and I even sleep with socks in my own bed at home in the winter. I expect that it would remain comfortable well down into the teens (Fahrenheit), not sure about the single digits. People complain about the bulk. It is kind of bulky, but if you want to go very small you have to pay two or three times as much. I was happy with a bit of bulk (it is less bulky than many others) and the lower price tag.

          Good Bag

          • Familiarity: I've used it several times

          Good bag for the money. Wouldn't recommend for backpacking or hardcore campers as bag is relatively large and heavy. I haven't had the chance to use it in the sub 20 range, but I used it this summer/fall and it kept me warm and comfortable during multiple excursions.

          Pros: Warmth at a good price
          Nice looking bag. Really enjoyed the Malaia Gold/Flint color.
          Roomy for a mummy bag. I've had problems before in the room part, but this one did well.
          Loved the the half zipper on the other side. I could hop into the sleeping bag from either side. Very nice.

          Cons: I didn't like how the zipper sometimes catches
          Relatively large and heavy (Not much to complain about at this price range though. Just wouldn't use this if I was into hardcore hiking)

          Overall for someone looking for a good bag in this price range, go for it!

          Warm, durable but bulky

            This is a good synthetic bag, as far as synthetics go. It is really warm when all draw strings done up however I only use it for base camp or short guiding trips as it is just to bulky for serious missions - thus the problem with synthetics... still , if synthetic and spring are your thing and you can take the bulk, its a good one :)

            Really warm bag

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

            I researched a lot and had a good experience with the backcountry staff to pick out a solid bag for winter camping. We took ours out this past weekend (Dec - 27th) to Wisconsin, and the weather was snowy and really frigid. The bag was cozy and warm in our tent (which really isn't winter friendly). I found the bags to be surprisingly pack-able, contrary to some of the reviews. It is a little large for backpacking but totally capable of it. Overall, really warm bag for the $.

            Side note, Who has a recommendation for a better stuff sack that'll fit? the Marmot one has trouble closing at the top.

            Best Bag I've Ever Used...Ever!!!!!

              I ordered this bag at around 3:30 PM on Thursday, August 28, 2014. I received this bag at around 10 AM on Friday after selecting next day air. Sarah O. did and amazing job walking me through everything in the process and waaay exceeded my expectations as far as customer service is concerned. But I digress, I bought this bag to use backpacking the Cloud Peak Wilderness Area in Wyoming. If you are at all familiar with Wyoming weather you know that snow in August is just as normal as snow on Christmas. We hiked in Saturday evening and made camp after getting soaked in the river crossing. I have never been so comfortable in a sleeping bag in my life. I get cold really easy and this bag actually kept me warm enough to pop my arms out for a bit. That was just the beginning of the Awesome-ness of this bag. The next day it rained all day and when we made camp at Misty Moon Lake it started to hail, and then snow. That night it got to a frigid 23 degrees F and the wind and snow would not let up. This bag kept me warm all night. It packs down perfectly and the features it boasts are not short of perfect. (On a side note, I am Type 1 Diabetic and it managed to keep my insulin from freezing as well) In short this bag was not only comfortable, packable, and warm but it very well saved my life. I couldn't be more happy with this bag, or with Backcountry and with Sarah O. This is the best purchase I have ever made.

              Great bag, great warmth. Bulky.

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

              This bag excels at keeping me warm, and fits true to my body. I have a slim to athletic build and I have space to turn in the bag. If I had much bigger shoulders, I could see it being a potential problem.

              The bag is bulky, and the Marmot stuff sack it came with barely fits the bag inside. With that combination, once the sleeping bag is in the stuff sack, it doesn't compress much. However, I think it would compress A LOT more if the stuff sack were a little wider. Something to think about.

              With the the included sack, probably not a great sleeping bag for backpacking, but an excellent choice if you're not having to travel far with it. And as I said above, if you had a larger stuff sack it would probably compress quite a bit more.

              Overall, I'm very happy with the bag and look forward to a lot of cozy nights in the Cascade Mountains thanks to this bag.

              Bulky, but Warm

              • Familiarity: I've used it several times

              As many have said before, this bag is a little heavy/bulky for backpacking; but, it does fit into the compression sack pretty well and compresses well enough to fit sideways in the bottom of my 75L REI pack. It is very warm- I camped in sub-freezing temps with a high fever with no problem. Great price, too. I just wish it was a little less bulky and heavy.

              Heavy for backpacking, but super warm

              • Familiarity: I've used it several times

              Great sleeping bag if you're looking for something warm and not too worried about space or weight.

              Used it in Gila National Forest, NM (car camping) and Pikes Peak, CO (backpacking) with temperatures between 10 and 25 degrees at night, and with a few layers on was sweating.

              Bag seems very durable and warm after about 20+ nights of use. While it is large and heavy it worked well when hiking up Pikes Peak.

              It's best uses seem to be car camping and for that it's perfect. If you're looking to backpack you probably want to find something lighter.

              Stuffs well into a Medium Sea to Summit eVent Compression Dry Sack

              5 star rating for car camping, loses a couple stars if you're taking it backpacking though.

              If you have a right zip and a left zip can they be zipped together to make a tandem bag? I know that with some Big Agnes bags this can be done, but that also comes with a much larger price tag.

              i hear the biggest complaint is the weight and stuff sack. I don't care so much about the weight but i want to make sure it will fit in my pack and not take up all the room... Does it come with a sack that can be cinched tighter or is there a stuff sack you reccommend that will fit this bag?

              The sack that comes with this does not really do an extra cinch. There are plenty of different compression sacks out there. I think the best way to pack this bag is put in some heavy stuff then stuff the sleeping bag around it, it will take up any dead space and still compress down pretty well. Then put stuff on top of it. Good luck!

              your trestles o degree synthetic dark rust long x wide is 62 in but the regular is the same also the length why ????

              Best Answer

              Richard, sorry for the site being off. We will get our specs updated. Here is the info you need:

              So the Long version fits up to 78" versus the regular which is 72".

              The long version in terms of width is 64" for shoulder girth and 60" for hip. The regular is 62" in the shoulder and 58" in hip.

              The wide version is 70" in shoulder girth and 66" in the hip.
