Product Reviews

Rated 1 out of 5 by from Update to my initial review on 07/02/23 After waiting 3 months (the entire summer) for a repair to my brand-new sleeping bag, Therm-A-Rest finally sent back the bag, saying it had been fixed. However, the tear in the sewing was still there, untouched. They basically kept my bag for 3 months and re-stashed it in a box (not even in the storing bag) without looking at it. What I was considering to be a bad luck when I bought this bag turned out to be a real lack of professionalism from a company that "has a very robust warranty and stands behind [their] product". If you are searching for a high-quality product, I can only recommend going somewhere else.

Rated 2 out of 5 by from Love /hate this bag Been using this bag for a year now. Warmer conditions it’s fine. But anything close to 30° or lower plan on freezing. I always have to add a liner and layers of clothing to stay warm. You can take a flashlight and see the down is not evenly distributed or none in some places.

Rated 5 out of 5 by from Best Bag Went on 35 days of wilderness canoe trips covering 500+ miles of Canada this summer and couldn’t have asked for a better bag. Temp regulation is great, when it’s hot, doesn’t feel too hot, when you’re hypothermic, this thing immediately warmed me up. Bag dries quickly when damp. Truly couldn’t have gotten a better bag, little pricy, but can tell this will last me a long time.

Rated 5 out of 5 by from Great bag Super cozy and warm, zippers work quite well, and plenty of room for your feet. 10/10 would recommend.

Rated 5 out of 5 by from Sliced bread has some competition This is without a doubt one of the easiest reviews I will write. Pros: The fabric is as smooth as butter making a lovely nights rest! The bag itself is plenty toasty (lowest I've taken this bag to is 28 degrees) Plenty of leg room to stretch out a bit while the bag is fully zipped repels a bit of water (single wall tent unfortunately drenched me but hey, I stayed dry in my bag at least!) and best of all packs down to about the size of a 32oz Nalgene bottle! Cons: None at this moment! Maybe the fact that I didn't get the 0F bag? Highly recommend this bag!

Rated 5 out of 5 by from Soft and comfortable! Roomy for side sleepers COMFORT: First off let me state that this bag is not made of some super thin sticky nylon like some ultralight bags are. This very soft to the touch and extremely comfortable. I actually prefer the way it feels to my actual bed at home that we have spent thousands on. The bag lofts up nice and thick and looks very inviting and actually makes you excited to snuggle down in it for sleep. In addition, the bag is very roomy. It doesn’t feel constricting like typical mummy bags. If you are a side sleeper or toss and turn I HIGHLY SUGGEST YOU GET THE LONG VERSION of this bag even if you don’t need it for height. The main reason is that the long version of this bag is also wider in the foot box than the regular length. This provides quite a bit more comfort for those of us who move around a lot at night. Even though the long bag says it’s for 6’6” people I’m 5’ 10” and this allows me to snuggle down into the bag and pull it over my head for warmth as well as leaving me the option to store gear in the bottom to prevent it from freezing. Had I got the regular length it would have forced me to sleep with my head outside exposed and left no room in the foot box. TEMPERATURE RATING TEST: It’s October now and we recently had some cooler weather move in for a couple of days so I used it as an opportunity to test the bag and my new sleep pad. According to accuweather temps dipped down to 40*. I slept outside on our deck to test this bag. First I laid down a thin blanket to prevent any damage to my thermarest from splinters or such. Next was my thermarest neo-air xlite. Finally, this bag which is comfort rated to 32* when you wear appropriate base layers. As stated above, the temps supposedly dipped down to 40* and I chose to wear nothing but my boxer briefs as I figured if I stayed warm then I should have no problem staying warm to 32* with wool base layers as the rating suggest. I can confirm that the bag worked great. No issues whatsoever. I slept all night in the bag and never got cold. Starting off the night when it was around 48* I was actually too hot and had to unzip the bag. At about 7am when temps were at their low I stayed zipped inside but stayed comfortable. The biggest surprise to me was that I didn’t get cold feet. I don’t think I have ever slept outside and not got cold feet. And this is while wearing thick wool socks. Often 2 pair of them! In this sleeping bag I wore no socks at all and my feet stayed warm. This was a pleasant surprise. I now have no worries as winter progresses that this bag will do just fine in lower temps so long as I wear appropriate clothing as suggested. CONCLUSION: In conclusion, if you like to move around at night and don’t like a typical mummy bag this is the one you should get. It’s very roomy and never once did I feel confined. I rolled and tossed all over the place and stayed warm and cozy. I spent hours searching for something lighter and while you may find something a few ounces lighter than this bag it will cost twice as much and will be about a foot narrower in the foot box. I hope thermarest never stops making these bags. I want to save up for the 0* version now for those really cold nights. I now have a thermarest xlite pad, this thermarest sleeping bag, and a thermarest pillow and none of them have disappointed me. At this point I don’t think I would hesitate to buy anything thermarest offers if I needed it because it’s clear their gear is well thought out and quality made.

Rated 5 out of 5 by from Keeps me warm and packs small! I bought this a month ago for a bike packing trip and happy to report it did so well! Packs up small and kept me comfortable in 45 degree nights (I got the 20 degree sleeping bag and get cold easily). Definitely pricey but it’s a phenomenal bag

Rated 4 out of 5 by from Nice bag but not perfect I tried this bag out a few weeks ago on a tent camping trip in Leadville, CO. With over night lows in the 30’s it kept my warm but not toasty. I do like that it is very light weight and can fit into a backpack. This sleeping bag is good I just wish it was a little bit warmer.
