Marmot  Trestles 15 Sleeping Bag

I purchased this bag with the expectation that I would be sleeping outside (without a tent) for four nights in weather below freezing on the Mt. Whitney trail. With the Marmot Trestles +15 bag I slept great, stayed warm, and got to see the stars on clear nights. Although the wind picked up to around 20 miles per hour, I did not feel a bit of cold. My only advice if you like to sleep outside is wear a face mask. I did have a user malfunction. One of the side zippers split open when I placed my elbow on it. Although this happened at 3 a.m., it only took a few minutes to repair my mistake. Great Bag, Great Experience, Great Price.

I bought this bag and immediately took it out for a test run. I'm a hammock camper and used this in addition to some other insulation/wind cutting systems to stay warm. First night was down below 20 near a water source and second night was about 20 in a windy area. The bag performed well in both. The only cons I found are size/weight (which is the trade off for such a good bag for the price). I'd recommend a larger pack if you want to do a multi day trip with this bag. If you are testing the limits of the bag, I'd recommend pads/underquilts/secondary systems to utilize the bags insulation effectively.

Bought this for a hunting trip in Colorado next to Mt. Princeton. Hiked up from 8,000 to 12,000 feet and slept overnight- once with a tent and once without, on the ground. The temperature was anywhere from 25-40 degrees while I slept, with winds up to about 20 mph. I was very comfortable and did not need my pants or jacket on, either in or out of our tent. I also succumbed the shell/stuff bag to scraping rocks and sharp sticks on the climb up, and the bag didn't tear or show signs of wear/scratches at all. Great sleeping bag overall. Very durable and comfortable! Worth every dollar-I will use this for years to come.

perhaps im a little strange but i dont see a problem with the heat rating, i have experienced very many cold nights with no bag period so i may be bias...however, ive been on many sub freezing trips with this bag and am very very happy with it. also, in the 2 years ive owned this bag ive never had a problem packing it to size. im not normally an advocate of stuff sacks for sleeping bags but i cant comfortly fit this bad boy in the bottom compartment of my gregory z40 or my ocp med rucksack. for price and performance I would recomend this bag to anyone!

Did an overnight backpack trip with 15 degrees outside and cold windy, wet snow. Tent was probably 30 degrees since water didn't freeze much. Bag was warm and roomy, and the bit of moisture on the bottom and insides of the tent didn't affect the insulation much. I'm a pretty lean guy so there was extra room. I never felt constrained, which besides warmth, was the most important characteristic for me.

I have had this bag for a little over a year and the insulation is coming apart. The fibers are short staple and were never particularly lofty to begin with. Marmot uses a generic budget-level synthetic fill in this bag. It would be alright if it were quilted tighter, but the loose shingle construction allows the insulation to fold around itself and break apart after some use. For me it has become all but unuseable outside of a casual late spring/summer bag. If you are looking for similar quality to this, you can find it in a cheaper bag from Eureka. If you want to get something that is going to last longer and maintain more loft than this I recommend the North Face Snow Leopard/Cat's Meow bags or something from Big Agnes.

I bought this bag to use for winter bivs. I am a member of a search and rescue group and we need to be prepared to 'shelter in place' in any weather. Although I hope I don't have to do this, I need to be prepared for it. Thus, I am not an avid backpacker that is willing to shell out big $$ for a bag when I hope it won't get much use, I want to be comfortable if I do. Thus, it is a decent balance between warmth and weight. I have tried it one night when the temp was about 30F and was very comfortable.

I've had this sleeping bag for 2 years and have used it on multiple (15+) backpacking trips (including thru hikes), in the snow as well as humid summer in the upper Midwest. Paired with a sleeping pad and appropriate gear, I have slept warm and comfortably at overnight temps down to 5 degrees F, even when it has gotten wet from tent condensation. On hot nights, I have unzipped both sides and stayed comfy. It packs snugly into the bottom sleeping bag compartment of my 40-L pack. The material has held up well to a lot of use by multiple people (loaning it out to friends). The only downside, in my opinion, is the weight. It's a little bit hefty. But for the price and performance, the weight is easily overlooked for me. In fact, we've decided to have my husband start using this one instead of an old over-sized bag and I just bought the women's version of the Trestles 15 for myself.

Been using this bag with no problems car camping for awhile. It excels in moderate temps above 30 degrees. Took it on a two day camping trip in the White Mountains this past weekend with both nights between 15 and 18 degrees. Zipper was VERY drafty, mummy hood pulls are not good, and the zippers often would press against my face in the night. I was freezing both nights even wrapped in all my layers. It fails at or near 15-20 degrees, the previous posters never mentioned testing its temp rating. Besides that its an ok bag, just don't get it expecting to do much comfortable cold weather camping. This is pretty much Marmot's cheap entry level bag so not knocking the brand. Its really a 4 lb 30 degree bag in my opinion. Taking this one back.

Purchased the Women's Trestles 15 to replace a unisex synthetic bag from another manufacturer (who will be unnamed). My favorite sleeping bag so far! The highlights: -Packs down into the provided stuff sack to fit nicely into the bottom of my 50L backpack -Fairly lightweight for it's temperature rating -GREAT for shorter women - I am only 5'1" and I don't feel like I'm swimming in it -Stash pocket on inside of the bag adds a nice spot to store electronics or small items (contacts, etc.) -Durable and quality construction - nothing on this bag feels cheap Overall an awesome bag that I'm sure I'll have for many years to come!
