Rated 5 out of 5 by from Magic in a bag! I took this bag for a spin in the Andes Mountains when I did the 4 day Inca trail hike in the beginning of October, and it worked like a freakin DREAM! October is close to the beginning of the rainy season in Peru and Bolivia, so the temps easily dipped into the low 30's at night with wet tents when it rained, but I didn't feel a thing in this bag. I bought a liner because I run cold, but it was really overkill and unnecessary. I'm 5'2 so the regular size was ideal for me. I haven't tried it in the summer yet, but I think it'll most likely run hot since it did so well in low temps. Not a deal breaker for me, I'll just open it up if I need to. This bag definitely gave me all the bang for my buck.

Rated 4 out of 5 by from So far so good! I bought this bag as an upgrade for my previous bag and having only used it once so far I'm impressed! I ended up purchasing the long since I'm exactly 5'6 and it gives me the perfect amount of wiggle room for my feet and space to stash my clothes for the next morning. I've always been an extremely cold sleeper so when I went out for an early spring mountain backpacking trip I was a little worried I would get cold. Temps dipped into the low 30s but I stayed warm all night! Only issue I had was that my neck got a bit cold since there's no draft collar but other than that it was perfect.

Rated 4 out of 5 by from Warm, light, but a little smelly This bag is light and packs down well, I have used it on a couple backpacking trips in the summer and got a little overheated in it. I recommend a mummy liner if not wearing long pants, as the nylon feels almost sticky against bare skin. (In warmer months I'll use a microfiber cocoon liner and unzip the bag) I brought this to a cabin in northern michigan in the wintertime which kept me warm when our wood stove wasn't cutting it. Also I noticed after a couple days, and in humid conditions, it can smell a little due to the nature of it being a down bag. Running it in the dryer on air fluff gets rid of the smell easily, I have not had to actually wash it yet after owning it for a year.

Rated 4 out of 5 by from Good go-to This is a very comfortable, roomy bag that packs down quite small, especially if you have a stuff sack. I used this bag on a hiking trip which was about 30 degrees in the late evening and 58 or 60 in the late morning. When we set up camp, the wind was relentlessly violent and I had experienced mild hypothermia. I crawled into this bag and synched it up and within a couple of hours I was ok. Because my tent was drafty, I did feel some wind chill through the bag, but the bag itself retained heat very well. I never fully emerged, even when the sun was shining down on the tent. If you get cold very easily, I would not recommend this sleeping bag in very extreme weather. I would use it until mid fall, assuming weather conditions are mild.

Rated 5 out of 5 by from Great bag! I have really liked this sleeping bag thus far. The stuff sack is pretty big, so I bought a compression sac to get it down in size and it does pack well. It's very comfy and cozy, and the water-resistant side panels helped when their was moisture accumulating on the sides of the tent in humid and rainy Peru! I was warm all night in this bag in humid 30 or so degree weather and a cheap pad underneath to boot.

Rated 5 out of 5 by from Loved on the AT My boyfriend and I splurged on these bags (the Joule and Igneo) for our AT thru-hike and are so glad we did. They were light, warm, and comfortable the whole way, even if they got a little wet. I never once noticed any wetness inside the bag, no matter what the bag went through. We carried liners for when the temperatures got below freezing, but zipping up the bag and cinching the top kept the heat in. They were absolutely worth the investment- I couldn't have done the trail without the amazing sleep I got in this bag!

Rated 5 out of 5 by from The regular actually fits a 5'6. I just bought this sleeping bag. Have used it a couple of times, both backpacking and car camping. It is definitely lightweight, soft and comfortable. And it has kept me warm, however I haven't really tested the cold weather yet. BUT I got the regular size, and I am 5'6 so I was nervous that it would be just too short. I am happy to report that I comfortably fit in it and my feet can easily hang in a relaxed position without hitting the bottom of the bag. I think we will be great friends!

Rated 5 out of 5 by from Best Weight to Warmth Ratio at a Great Price! I bought this bag to replace my Marmot Angelfire (rated EN comfort 32) after it sprouted so many leaks I couldn't move without sending feathers flying into the air. I spent countless hours comparing all the different bags on the market and finally decided to try it after feeling that considering I was gaining nearly 10 degrees and shedding a pound off of my old bag weight, the price was too good to be true. There are $500+ bags on the market that are only a hare's breadth lighter and not rated as warm. I took it for an eight night July adventure into the Sierras. I sleep very very cold and usually employ all the tricks (hot rocks in my tent, water bottles, long underwear, sleeping bag liner) so with that in mind, I have never been able to sleep comfortably close a bag's rating (comfort rating, that is... forget about the men's ratings). I can happily report that after several extremely cold nights around 12,000 ft with some snowfall during the day, I was just fine. I was considerably warmer than I have been in the past and I didn't have another body in my tent to help warm me up. I had also upgraded my sleeping pad to 3.7 so that helped some, but I mostly think it was this bag. On the coldest night (it was probably in the low 20s) I did feel some cold through the zipper side, but not much. I took this out again for another trip in Big Sur (nights in the 50s) and I had to sleep with the zipper down, which is very unusual for me. The stuff sack it comes with is large but I replaced it with an 11L ultralight compression sack and it synched right down. Lastly, my two small complaints are that the material is not as silky as my old Marmot bag and it doesn't have a draft collar, which I miss. Other than that -- great bag!

I am 5'6" exactly. Would you recommend the regular or long size? I don't want to be overly snug, but also do not want too much extra room that will trap cold air.

Asked by: LL91
The regular Joule Sleeping Bag fits someone up to 66 inches so it will fit, but a long bag will provide more room inside and will be a more comfortable fit.

If I am using the 15L compression sack, what are the dimensions of this sack compressed down?

Asked by: Sydney
​The compressed measurements can vary depending how hard the straps on the compression sack are pulled. Fully compressed, the stuff will measure approximately 8.25 x 9 inches.
