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

Zip Compatible!

  • Familiarity: I gave it as a gift, but have feedback to share

I bought two of these for my best friends wedding gift, with opposite zips these bad boys can be connected and she is super excited to get some use out of them! They pack pretty well too if you're not going on any long excursions. Car camping and quick trip friendly for sure!

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

Very decent

  • Familiarity: I've used it several times

I've used it several times now. I bought a long version, which turned out to be very good choice for someone who doesn't like mummy type sleeping bags. I'm around 189cm, and it does not feel 'tight' like a regular mummy. For me it counts in plus.

It is very well made, and you can tell that from the very first time you use it. It is BIG though (maybe it's just long version), and it takes out about half of my pack's volume. This is part I don't like. I don't mind weight that much, but it just takes a lot of space. If you're planning to use it for camping, using a car to do most of carrying, you'd be ok, otherwise get yourself something that does pack up smaller.
I was surprised to discover, that somehow it works pretty well in even in warm rooms (meaning you don't get super overheated). I was expecting having massive problems falling asleep in a room with temps around 22*C, but it turned out all that was needed was to unzip part of the zipper.

+ Quality materials,
+ Very good craftsmanship,
+ Long and spacy (once unrolled)
+ Works pretty well in various temperature conditions
+ There's a lots of filling, which comes in handy when you forget your sleeping pad.

- Bit heavy
- BIG, even when compressed

Replaced my original

  • Familiarity: I've used it several times

I have been known to sleep in my spring bag in 20 degree weather and be comfortable. My original Trestles 15 I froze my butt off in weather above freezing - no ice in the AM - which I found rather odd. So odd I contacted Marmot who immediately after asking a several questions sent me a replacement. I suspect maybe a fill issue on some production run? Dunno exactly but customer service was good. I have not been in weather below about 38 degrees since but been very comfortable. Awaiting another cold night to see my results.

The bag is great overall. Good material, packs up easily, zipper leaves something to be desired. I am 6'2" 255 and have a long wide version what is quite comfortable for sizing.

Great bag overall!
I haven't really taken it to the extreme, but camped in about 25 degree weather in a really old tent that let a lot of rain in, but I stayed warm, dry, and asleep until morning when my friends and I discovered the puddle we'd been sleeping in.
I'm 5'8", female, and there was plenty of room in the bottom for heating up my clothes for the next day.
4 stars given because zipper caught often, but otherwise would give it 5 stars!

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

Responded on

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.

Great Sleeping Bag

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

I purchased this sleeping bad for a camping trip in Maine this summer. It was super comfortable and kept me warm on chilly, rainy nights. Great buy!

Best sleeping bag money can buy

I went to college in Ely, MN...The Boundary Waters. I bought this sleeping bag from a local outfitter the spring after my fist year in college, spring of '08. Since then, I've spent easily over 1,000 nights in it. I have paddled the BWCAW and hiked the Superior Hiking Trail instructing for Outward Bound. I have Kayaked the Apostle Islands of Lake Superior guiding with Living Adventure Inc in Bayfield, WI. I have spent many a sub-zero night dogsled guiding in the SNF and BWCAW with White Wilderness Sled Dog Adventures. This bag has stuck with me through it all; I have literally put it through the Wringer! I'm what they call a "human furnace", and even on the hottest, muggiest nights Ive been comfy...just open that puppy up or lay on top of it. I use it as the liner bag inside my -15 bag when the temperature plummets to -45, and sleep right through the night. It has visibly lost loft since I purchased it, yet for the past two Octobers my Marmot trestles 15 has been my best friend on month long canoe expeditions in the Quetico Provincial park, where the temps ranged from mid 80s to low teens. This past Quetico trip we had only 6 days of sunshine the entire month, the rest of the time it was 38 and pouring rain, or snowing on us. The last two days we had to break through 1 1/2 inches of ice on the lakes to get out of the Quetico. Let me pause here to mention that we slept in HAMMOCKS the entire month. I Cannot adequately express how impressed I have been and still am with this sleeping bag. I'm 6 foot and 170 lbs; the regular is plenty wide for me and there's room in the foot for some extra clothes to preheat 'em for the morning
Bottom line. Buy this bag; its the best one money can buy.

Very warm bag

I got this bag on sale, and have since used it for a good amount of high altitude backpacking in Pisgah National Forrest (NC). Definitely a little warm to be considered a 3 season bag, but is nice and toasty during those long winter nights. Doesn't pack extremely small, but fits snugly into the bottom of my Osprey Atmos 65. I would recommend this bag for anyone who expects to be out in the back country with temps under 30.

I need a 3 season bag that stuffs small

Best Answer Responded on

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.

Responded on

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!

Responded on

I'd probably just go with the Long rather than the x-wide. Although you will have more room that is also more airspace that your body has to heat up so you may find the bag a bit chilly with the extra volume.

Responded on

I am 6'2" 265 with a 48 chest. The Long Wide is great for me and comfortable.

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 Responded on

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.

Responded on

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?

Best Answer Responded on

Yep, if they have opposing zippers.

Responded on

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.

Excellent all-rounder

It's not the lightest bag, it's not the warmest in the 15-degree range, and it doesn't have some of the cool features of the other bags. That said, it's a pretty bomber bag that will put up with just about everything you can do. If you want to haul it, you can certainly take it backpacking. It sits nicely in the trunk of the car, and is right at home on your buddy's couch. It's not too warm to lay on top of all summer, and will keep you warm well into the 20s if you're smart about your layers and pad. It's a bag that I don't have to think about. I don't have to worry about it getting wet, I don't care if it gets dirty, and the zipper always works. It's right at home on the back of my bike on overnighters and short tours. I like this bag a lot. It doesn't excel anywhere, but it's one of the best all-around bags for the price.

Trestles 15 Sleeping Bag

I've had my Trestles 15 for several years now, and sleep in it 20 to 30 nights per year. It's a durable bag, well built, but the 15 degree rating is certainly low. A 30 F rating is more accurate, unless you sleep in long johns, a fleece jacket and stocking cap.

Like many bags, the width/volume of the bag is too large, so you have to heat a lot of dead air space. To be more efficient the bag should have the insulation closer to the body.

Perhaps sleeping bag makers are adjusting their bag sizes to fit the increasing girth of their customers.

All-in-all, it's a great bag at a decent price for late spring through early fall conditions here in northern Minnesota.

warm and soft yet small and light

Awesome! This was great for a desert camping trip in the spring. It kept me nice and warm so I could sleep like a baby with its soft and comfortable feel. Should be great for spring, summer, and fall adventures. Come winter this will be great for crashing on friends floors when bouncing from resort to resort looking for the gnar.
