Marmot Trestles 15

Summary

An absolute bargain to offer this warmly-rated a bag for an entry-level price, though the 15-degree rating may be a little optimistic.

I've been using a pair of older sleeping bags for years, and it wasn't until recently I purchased a set of these Marmot bags as their replacements. All I can say is, boy, has sleeping bag technology come a long way in that time. 

My last bag was packed by folding it in half, rolling it, and using the attached elastic straps to secure the rolled shape. 

The bag comes with its own compression bag, which compresses the bag on the X, Y, and Z-axes. 

A.) You don't have to roll it. Stuff it however you'd like or are able to, into the bag, and done, and

B.) Tighten the four nylon compression straps to your liking. 

Being a synthetic fill, it is a heavier and bulkier bag. Even with the compression bag, the smallest it packs down to is the size of a basketball or so. Not ideal for backpacking, but for car camping, a vast improvement upon old technology.

Mind you, one you get it home, you'll want to take it right out of the compression bag, air (and perhaps clean) it out, and hang it properly. Keeping it stuffed tight in the bag will cause it to lose loft over time. The attached hanging loops at the end are a nice idea, but are only small enough to fit on certain hangers, and even then, have a tendency to slip off. I fold mine loosely in thirds, stack them atop another, and place them in a corner of my room away from direct sunlight and the heating vent.

I purchased a men's size long. I'm an even six feet tall, which is a difficult height to be for these bags. The regular size is a tight squeeze, while this long size is a little too much. I find myself having to tuck the excess under myself. I suppose it would be a nice place to put a boiled waterbottle on a cold night, but barring that, I can't see it as a positive thing. 

One zipper is a full-length, while the other runs about a third of the length down the bag's side. These dual zips are handy for easy entry and exit from the bag, as well as temperature adjustment when the nights grow warmer or cooler. I know there's an option to join bags together, but owning a Men's Long and Women's Regular, I can't see how these would be remotely close to another in size for this to work.

Being a side and/or stomach sleeper, I don't have much use for this in the intended style, so I can't speak for the functionality or fit of the hood. 

I will say the temperature rating may be a bit optimistic. My buddy and I went camping on a rainy, windy night in the upper 30's, and if it weren't for a fleece sleeping bag liner, I'd have been too cold in this bag. This may be due to the fact I don't zip it all the way up, but then again, it wasn't my face or upper body that was coldest.

All in all, this is the best bag you'll get for the money. I don't know where else you'd find a bag rated so warmly with as many features for this good a value.

Summary

VERY warm. Used this bag in the Grand Canyon when temps were in the 10°F range for several nights. Bag was super cozy and I wasn't cold any of those nights.

This bag, for the price, is excellent. It might not be as light as some others, but for $100 you can't beat its warmth and compression. 

Summary

A warm, synthetic fill bag that keeps out the cold, but packs up poorly.

The bag was purchased to replace a worn-out summer sleeping bag with a real 3-season bag, and I have used it throughout Quebec in some chilly, rainy weather in Gaspesie and Monts Groulx, and some frosty mornings while car camping north of Lac St-Jean for about 6 months.

This bag is plenty warm, with a hood that keeps out all drafts. I purchased the long sized bag, but really, at 6'1, the long is too long — there is so much room in the footbox that my feet really can't warm up that space, so I have to tuck it around.

Getting in and out was never a problem, and so far the bag has not shown any signs of wear.

The big drawback of the bag is the packed size; I exect a synthetic bag to be bulky, but this bag, when compressed, most resembled a bowling ball in my backpack, taking up more space than I could afford.

Summary

Great bag. Good for 30 degrees.

Very good bag. NO more rolling up to pack it, just stuff it in a sack! Awesome. Generally it's good for about 30 degrees, but I am always cold. 

IF YOU ARE INTENDING ON CONNECTING THIS WITH ANOTHER MARMOT BAG LOOK AT THE LENGTHS!!!!! We bought a men's medium and a women's medium and when we went to zip them together the men's was 4-6 inches longer. We are still able to link them but there is overhang. 

This is actually a great bag.  I have had it now for 2 years and have used it extensively and it barely shows any wear.  I have used it in temp ranges from 15 degrees to 55 degrees and have never been uncomfortable.  

I love the fact that you can control the climate in the bag!  The one side you can zip the bag down a quarter way and the other side is a full zip.  When the temps are warmer, you can unzip both sides and fold the top back.  When the temps are colder you can zip it completely up and be comfortable.     

As far as getting cold, you have to take into consideration how you sleep normally.  If you sleep warm like I do, then a 15 degree bag will work down to 15 degrees and maybe lower depending on how you dress and if you buy a liner (a use a cotton Alps Mountaineering liner mostly to keep the inside of my bag from stinking and wearing out).  If you sleep cold (meaning that you need to wear extra covers) then you would be better off buying a zero degree bag.  Everybody sleeps at different temps and when buying a bag you must know how you sleep.

I have also read reviews on the zippers getting stuck.  This reviews usually come from those who do not know how to use a zipper in a bag.  I have never had any issues with the zipper!

In the end, this bag is warm and roomy and of very good quality.  I would recommend buying this bag (my dad also bought one this year after using mine for a cold weekend) to any one.  

Also, store your bag unrolled (in a storage bin or under your bed).  If you keep a bag rolled up, the insulation slowly decompresses over time and your bag will not keep you warm.  Even after 6 months, your bag will not be as efficient! 

I live in New Zealand, and have used a Marmot Trestles 15 for the past 3 years. It's my first really good sleeping bag, so I don't have much to compare it to. 

It's been a really good bag, good for using inside the huts, where it's quite warm. But I usually prefer to sleep outside, using a bivvy bag. In freezing conditions, in Trestles 15 and bivvy bag, I am only warm enough if I have piles of clothes on as well, and then I have to huddle in a kind of foetal position. I am female, and a very cold sleeper. 

I like my Trestles bag,  it is very good quality but I am soon going to try a down bag.

I had a Cat's Meow 20F that I froze in the first night (fully clothed, in a wooden shelter, at about 40F) and just about every night after that; I was cold even in mild (60F) conditions. 

After more than 30 nights in it I finally gave up on it and got a Marmot Trestles 15F long extra wide.  I was concerned about the weight but did not notice it at all on a week-long 50 mile hike. The extra weight is more than compensated for by the quality of sleep I now get.  I am comfortable in just boxers and a tee even at 35 deg F.  Not ultralight, but it definitely is ultraplush. I love my Marmot Trestles 15F.

I was worried that I would be too hot in it, but that has not been a problem; although I have never used it above 65F.

My son has one; his friend has one.  We all love 'em.

This bag is great in temperatures around 30F. My fiancee and I (she has the women's Trestle 15) tried it in the high 20s this past weekend and had pretty chilly feet by morning. We are going to give one more try in the colder temps and see if making some changes to our sleeping configurations might make the difference. If it doesn't work, I'm going to see if I can't return them or sell them and get some warmer bags.

We do like the mateable feature for warmer temps (around 40F) but won't dare do it below 35F. They also stuff down pretty small for synthetic bags and just barely fit in our sleeping bag compartments on our backpacks but they're pretty roomy bags. The pocket inside is pretty big and will hold a lot but the velcro closure on it is small and stuff can slide past it and fall out (like a phone or ultra compact camera).

In the end it all depends on if you sleep warm or cold. If you need more warmth, try down. That's where we'll go next.

Although i live in virginia and hike mainly in summers, I wanted a cold weather bag that wouldnt break the bank. My prayers were answered with the new Trestle line by Marmot. The first weekend i bought it in March i went camping during an unexpected cold snap ( 20 degrees) and i actually had to unzip a bit to cool off.

While it may not have some of the bells and whistles of its more expensive brothers the Trestle is a steal. I paid 129 for the long extra-wide. The regular comes in at a paltry 99 bucks!!! while it does weigh 3.11 for the extra wide it stuffs nice and small and since it keeps true to its temp rating i dont have to worry about bringing too many extra clothes to keep warm while sleeping. Besides the weight the only drawbacks i can see are the fact that it doesnt unzip all the way which doesnt allow one to vent their feet, and i wish Marmot would have put a pillow pocket in it like it did with the other new bags. I mean glow in the dark zipper pulls are nice but id rather have a pillow pocket.. And while on the subject can all bag manufacturers take a cue from Sierra Design and put pad locks on all sleeping bags!!!!

This is a wonderful bag! My old Kelty was shredded after 10 years of use, and my softshell was Marmot so I decided to give their bags a try. Once again marmot didn't disappoint!

The only complaint I have is that I roll, and it's not super roomy! or else I would've given it 5 stars.

My Marmot Trestles has served me well for a couple of years, except for my early spring trips in Virginia. When temperatures dipped into the 20s on my first trip, I absolutely froze. I chalked it up to not having my wooly longjohns, but I still froze the next March when temps again fell into the 20's. Perhaps my experience is different from the other reviewers because I am a woman. I still rely on my Trestles for those damp trips in the late spring and early fall in Virginia, but I'm looking for something warmer for those colder nights.

This bag has all the quality workmanship I expect from Marmot. So I think it's a great buy for the price. On a late fall trip to Glacier Nat'l Park the temp dropped into the low 20s. I was very cold in this bag that night. Some of that has to to with my mostly mesh tent not being great for winter weather. Anyway, for me this is a great bag for the 30-50 temp range.

I've used this bag at below 0 a few times without a tent, full length ground pad only. I slept in layers and was chilly (feet) in the morning, but everything worked out ok. I typically handle colder temps well, so keep that in mind. It's very comfortable between 15-30 with next to nothing on. I would recommend this to anyone who 'might' camp a few nights near zero, but mostly at 10 degrees or above.

Great sleeping bag. Kept me very warm in all situations I've used it in so far. The reason I didn't give it 5 stars is that my wife, who is a cold sleeper, was cold when the temperatures hit the low 30's. So from what I have seen the temperature rating works for me who sleeps warm but not for my wife the cold sleeper. Great compressability and great value. All in all money well spent.

Good for 3-season conditions, but you need a good pad. I've slept on the -2 Celsius and the temperature inside the bag was perfect, but I've very cold feeling from the ground. I used normal 1-stratum pad - 10mm but actually that wasn't enough.
