Description

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

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.

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"

Hey Johnny,
Marmot says that you can zip together the long with the regular length and long as they are opposite side zippers.

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!

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

Responded on

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.

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.

WHY IS RATED FOR WOMEN? THAT IS, ALSO WORKS FOR MEN? ISN´T IT?

HEY ERICK,

I DO NOT SEE WHERE WE HAVE IT LISTED AS A WOMEN'S SPECIFIC BAG. AS LONG AS YOU FIT WITHIN THE SIZING SPECIFICATIONS LISTED IN THE TECH SPECS YOU SHOULD BE JUST FINE. I HOPE YOU HAVE A GREAT WEEKEND.

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.

Long and wide!?!

Finally a bag with a little more shoulder room.
Best backcountry sleep ever, I almost rolled around to much because of all the freedom, still packs small
Awesome

Zip Compatible!

  • Familiarity: I gave it as a gift

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.

Pros:
+ 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.

Cons:
- 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.

How big is it for backpacking? Does it take up a lot of room?

Snuggly!

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

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.
