Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

Had this for a few years now!
5 months ago
Ive had this since 2021 i believe (2025 now). I like it! I took it on a trip to AZ once. It was about 30F and I was pretty cold though. I am 5 ft tall so maybe it was just the extra space, cold air from the creek at our site, or I just had trouble warming back up. I try to fill the end/ fold it under to prevent this with any bag. Its usually pretty warm but I might get a liner for those colder nights. I like the extra little pocket, foot box shape, and zip on the side. To be fair, I haven't had another sleeping bag but for the price I suggest it! Packs down relatively well. Used it on all my trips and throughout an entire summer. Held up well so far, no complaints there.

Temperature rating not accurate
2 years ago
I bought the Trestles Elite 20 because of the packability and the COMFORT rating of -6.5C. I have yet to have a sleep sufficiently warm enough even around 4-5 celsius, which is the lowest I have used this bad. I am not a cold person in general, but with this bag I have to wear multiple sets of thermals, multiple socks, and I have even resorted to taking a hot water bottle to bed to try and stay warm. I have had to now return to using my Asolo and Coleman bags, which are surprisingly much more warm, and only slightly larger/heavier. I really wanted this bag to work but it doesn't perform as marketed, and I am really disappointed in this Marmot product.

Warm bag great for car camping
4 years ago
Took this car camping in the Olympics at 5400 ft where I slept in 25-35 F weather with rain, wind, and occasional snow in the morning. In order to stay warm and cozy, I needed to wear a thermal layer + sweater and sweatpants, and tuck my feet with socks into another fleece sweater. At 5'6" I had enough space to comfortably sleep, and tuck some extra clothes for the next day's hike in the feet - I wouldn't recommend it for anyone much taller. Very happy with how it kept out the wind for the most part, and how I was able to pull the mummy's face-hole tight so that warm air didn't escape.

Travelled 2600 miles and it never let me down
10 months ago
[This review was collected as part of a promotion.] I brought this sleeping bag with me on my thru-hike of the Pacific Crest Trail last summer. I slept in it for 150 nights and never let me down! Great balance between weight, warmth, and price. However, I found it very narrow. I like to sleep with my legs forming a figure 4 shape, but it was impossible to do in this bag. I also rotate like a rotisserie chicken during the night and I got tangled in it a few times. A little bit cold when temperatures drop towards 0°C, especially when the bottom of the bag is exposed, as it is less insulated than the top. I had to wear my puffy for those nights or wrap it around my bum to keep it warm. Finally, I found it a bit bulky but it is overall a great product! I would recommend it to thru-hikers on a budget or anyone going on shorter trips.

Comfy and warm.

Kept me warm on some pretty cold nights in Paragonia. I'm exactly 165 cm and have wide hips - it fits me great. I found the strings on the hood a bit tricky the first time I tried to tighten the hood (was the middle of the night though and I was sleepy). Best feature I've discovered so far is that it's water repellent - my friend's dog peed on the sleeping bag. I rinsed the area out with a hose for half a minute and in no time the sleeping bag was dry and with no trace of dog-pee smell or anything.

Snug like a bug!

[This review was collected as part of a promotion.] Only taken out for 1 camping trip since I bought this, but it was the most comfy sleep I've had in years. The fact that it's eco friendlier than most options really helped made my choice, more then other technical features. I was afraid it might be to cold. Not at all. It packs up alright, on the bigger side. I'd say perfect for car camping, decent for hiking trips! And it's eco friendly. If there's any doubt, that should help right? Any little change you can make will help!

Excellent and Eco!!
5 years ago
[This review was collected as part of a promotion.] I purchased this bag a month ago for a trip to Banff. As I get more and more invested in spending quality time out in nature, I feel a deeper and deeper responsibility to purchase only products that have the highest quality of eco/sustainability (plus cruelty free when can!) This sleeping bag was the best one I could find on the market right now! Was perfectly comfy and warm, and it compressed down super well—easily fit into my carry on since I flew into Canada.

A nice little eco sleeping bag
2 years ago
[This review was collected as part of a promotion.] The sleeping bag has been great for both backpacking and car camping. Held up (just) in below freezing temperatures and does well for warmer temperatures. Light, cozy, packs pretty small. Easily fits back in it's stuff sack. We like how the women's had a choice of zip side. Needed a synthetic sleeping bag as my partner is vegan and we're happy with the purchase :) reasonably priced too. Good size for us (160-175 cm), although a little snug across the bag

Great bag but not as soft as the Trestles 15
3 years ago
I bought this for my wife and as a back-up bag for when I take friends camping. I got a long so it was basically the same size as the men’s regular. I have the men’s Trestles 15 regular and I will say while this one is more money and lighter weight, the cheaper, slightly heavier 15 is way more comfortable. You can tell this one just isn’t as soft and comfortable. Idk why, maybe it’s the eco material. Other than that, it’s an excellent bag.
