Very warm, almost too warm.

I've used it once or twice and have initial impressions
True to size

First night was cold and the trestle kept me toasty warm. The overnight low was supposed to be around 40 but felt colder than that outdoors. I had to strip from my sleeping clothes but stayed in the mummy bag all night for warmth. The next night must have been warmer as I basically just slept on top of the sleeping bag, using just a normal blanket to cover. So I'd say first night was mid to upper 30s for the low and it kept me very warm. I was sleeping in my pull trailer (not an RV just a regular enclosed pull trailer). Might be a little bit more protection from the elements than a tent though which is why I mention it. Overall it performed quite well and am happy with it. Oh, I'm 5'8" and have quite a bit of room left at the feet. Not an issue just saying it seems you can be 6'8" and not have your toes cramped. So I will say runs true to size as I'm not a large dude.

Bad seams

I've used it several times

Good bag, except that the seams keep ripping, even with light handling. This bag has ripped in 3 different spots over fewer than 10 uses. My mom has repaired it once, and her comment was that the stitching Marmot selected was too weak. This last time, which prompted this review, the bag ripped in 2 spots, and it appears to be because they sewed the seams too close to edge of the fabric, so the fabric just pulled out and frayed, right by the zipper. Note, this happened during normal zipping of the bag, no forcing. If Marmot fixes the seams, it will be a good bag.

Awesome bag

I've used it several times

This Marmot Trestles 15 degree bag is the perfect all around bag in my opinion. I use it mainly in the summers when the temps get into the 40's in the high Uintas and it works out perfectly for me! I'm a fairly warm sleeper, but on real cold nights I add a bag liner to my setup and it adds about 10 degree's of warmth and i'm good to go. It's definitely not quite as warm or as packable as my 15 degree Marmot Helium, but worth the money savings for a great Synthetic Summer/Fall bag!

Desolation Wilderness

Just took this sleeping bag to Desolation Wilderness. Great, COZY, warm sleeping bag, but at a little over 4lbs, it was one of the heaviest things I took over the 15 mile backpacking trek.

Awesome Bag

o This sleeping bag is what dreams are made of! Perfect for all temperatures, and is an incredibly comfy! Warning… when you jump in this sleeping bag, you may not want to get out… I had my 6’1” boyfriend hop in to see how it fits him and he had more than enough room in it. We took this camping in 20 degrees (F), and it was perfect! I also bought the Big Agnes Insulated Air Core sleeping pad for those really chilly nights for a bit of additional warmth for those chilly fall nights. I am a huge fan of Marmot products and this bag reaffirmed my appreciation for the brand. I would highly recommend this to a buddy, it’s a great product!

This sleeping bag is great.

Got down to the low 30's this past weekend and I slept comfortably all through the night. Packs light and tight too. Highly recommend.

Poor performance at 45f

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

I love marmot products my last bag is still going strong after 10 years of heavy use it’s just getting compressed. The bag arrived and looked great no issues with manufacturing and it seems just as good as any other product I have from the company. I went out last night to the north country trail in MN just to give the bag a quick test. The bag packed well and lofted nicely after a day of being compressed. With little to no wind and just your average MN dampness in the air the bag was cold all night. The zipper seemed to let in more air than I would like when I moved around. The temp did not drop below 40f and I had to put on my down jacket just to stay warm at 1am. But I could not get comfortable so at 4:40am we packed up and headed out because I was just to cold. My wife slept just fine with the same sleeping pad and her SJK bag with the same rating. I have a climbing trip next week and will have to order something else since I do not trust this bag.

possibility something like of early stage of hypothermia before getting into sleeping bag.

Awesome Bag!

I've used it several times

This bag is great! I have been kept plenty warm (~30 Degrees). It compacts pretty well for a synthetic bag, not as good as down, but that is expected. I really like the fact that I can zip down both sides: full length on left side and down to my midsection on the right. If I am warm it allows for a bit more ventilation in the bag. The other thing that I really like is the footbox. I don't have huge feet, size 10, but it provides a little bit more space in the bag for my comfort.

Keeps me warm!

I've used it several times

I'm a car-dweller, and I currently sleep in this bag on a full-time basis. So far its been used in temperatures ranging from around 20-45 degrees F, and I've never been too cold or too warm. I'm a broad-shouldered guy, and the bag is a little narrow for me, but it zips open at the torso on both sides, making it still pretty comfortable. It compresses fairly well, and is relatively lightweight for a synthetic bag. For a dedicated backpacking/alpine bag I would probably want something lighter/more compressible, but as a car-camping/easy-backpacking bag it does the job, and it does it well. This is my second Marmot sleeping bag, and I've always been very impressed with the quality they deliver at such an affordable price.


Does this come with a stuff sack included?
