Details

  • REI double-protection design combines a polymer-coated down fill with waterproof/breathable fabric at the hood, sides and footbox—areas likely to touch a damp tent wall
  • Designed to fit a woman's body, this bag offers increased room at hips, decreased room at shoulders and extra insulation in critical heat-loss areas
  • Water-repellent 700-fill-power duck down offers superior loft and warmth
  • Ripstop nylon shell also uses a durable water repellent (DWR) finish to further protect the down fill
  • Performance fit keeps weight low and thermal efficiency high
  • REI in-the-round design puts vertical baffles in the sidewalls to wrap you in warmth and create a better fit than bags that use only horizontal baffles
  • Contoured hood, insulated face muffler and full-length draft tube all work to keep warmth in
  • Differentiated hood and neck drawcords simplify adjustments
  • Most REI backpacking bags can be zipped to other REI backpacking bags; women's bags zip on the right, unisex on the left
  • The women's REI Joule sleeping bag includes a nylon stuff sack and a large cotton storage bag

Imported.

Many sleeping bags are rated for temperature by an independent testing protocol, the European Norm (EN) 13537. Each bag gets two ratings: a Comfort rating and Lower limit rating. The Comfort rating is the lowest temperature at which the bag will keep the average woman (or "cold sleeper") comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep an average man (or “warm sleeper”) comfortable. Everyone's body and sleep comfort is different, so EN Ratings are merely a guideline to help you compare products.

Rated 4 out of 5 by from Super sleek summer bag When I received this bag, I was unsure of how I would like a 30 degree bag as I've been guiding with a 15 degree one for years in all seasons. I found myself pleasantly surprised, however-- the lighter heft sacrificed little as this bag kept me toasty warm at 10,000 feet in CO near snow and rang true to it's temperature rating. The outer shell of the bag is a refreshingly durable material and the loft of the down was pleasing. While there isn't a pocket for your contact case or whatnot inside that I found (it may still exist), it didn't matter overall to me. I haven't put the water-repellant down to a test but given the quality of the rest of the bag, I don't doubt it will hold its own.

Rated 4 out of 5 by from Lightweight, warm and super packable! So I needed a summer weight, lighter sleeping back for my backpacking adventures. The joule hit the spot. At 1lb 9oz. it dropped over a pound of weight from my 15 degree bag. The material on the bag feels really sturdy and i've had no shedding issues. The zipper gets occasionally stuck with the interior lining when zipping up (but i have never found a bag that doesn't do this). This bag also packed into a really small compression sack, so that in my sleeping back portion of my backpack I could also put my sleeping pad, pillow AND pack cover. I would like it to be slightly more breathable on the inside, felt like it stuck to me at points in the night. Otherwise it's a great bag and will be going on many more adventures with me.

Rated 5 out of 5 by from Great sleeping bag - has everything! This bag is really well designed. The first time I used it I noticed a few things... First, the bag is warm and has great loft but really light. Second, the smart zipper design is great and makes it so much easier to put back together. Third, and maybe this is because I have never had one before, but I love the neck scarf, muffler piece; I am someone who frequently gets cold, so being able to snuggle the bag around my face was awesome. I haven't yet tested the bag to the coldest nights because it is end of May, but seems very warm.

Rated 5 out of 5 by from Couldn't be happier! I bought a Kelty bag during the 20% sale last month on Wednesday, but ended up being far more impressed with the Joule 30 when I walked back into REI for the same sale that Friday. My boyfriend ended up getting the male complement before me, so we were surprised to find out that the two zip together! It packs relatively small, but I definitely suggest grabbing a waterproof compression bag to use for backpacking. A mesh bag is also included to properly store your bag between camping trips so you can save that down filling.

Rated 5 out of 5 by from Great in damp climates I've used this bag on two trips - two nights of car camping in the Smokies and two nights of backcountry camping in Southern Indiana. Both trips had high humidity with a night of heavy thunderstorms during one trip. The bag stayed lofted and the shell portions kept me dry, although it can feel a little clammy without a liner or long sleep pants. The position of the zipper lets the bag drape over you even when left unzipped. As a side/stomach sleeper who turns in my bag rather than pulling the bag with me, the hood structure let me breathe without feeling suffocated in fabric, but still stayed over my head. I also own the older, warmer version of the bag, and I like the improvements in this model. The zipper pull is much easier to use and the draft collar is comfortable and unobtrusive on a warm evening. As a bonus the blue color is a pretty jewel tone that doesn't really show up well in the online photos- a refreshing change from other gear colors. I'd recommend it for three-season backpacking sleeping bag for damp climates.

Rated 5 out of 5 by from Lightweight and cozy Lightweight and compresses down to a small, pack-able size. It allowed me to lose some pack weight on a rainy, spring backpacking trip. Stayed dry even when other gear in my pack got damp. High loft and roomy bag. Exterior is a little crinkly at first.

Rated 5 out of 5 by from Very light and lofty I've slept in this sleeping bag twice so far -- once in a hammock and once in a tent in May and June in Virginia. Because it was not very cold either night -- once cool and the other warm -- this sleeping bag was ideal. It compressed very small, the zipper did not zip up the inside of the bag, the loft returned even after compression. I love that there is a collar that will help keep warmth in. I haven't needed it, yet, but I know it will be veg helpful once I do. The foot box is large enough that I didn't feel like I had to angle my feet. I was even able to comfortably cross my ankles without squishing my feet or toes. The zipper pull is a sturdy plastic loop rather than a traditional zipper, which is great. The fabric is very smooth and comfy. My skin did not stick to it or catch on it at all. It's so slick that I did a fair amount of sliding around in the hammock, but it still worked well and was great in the tent on my sleeping pad. My only concern (which remains to be seen as I use the sleeping bag further) is that the down will be redistributed unevenly in use leaving spots too thin. So far I am very impressed and this sleeping bag will replace my current summer/spring sleeping bag.

Rated 4 out of 5 by from Lightweight, tough zipper I received this sleeping bag to test out. It went on 2 nights of backpacking and 3 nights of cast camping. Here are the pros and cons: Positives: -Very light weight. -Compacts down very small! There was extra room in my backpacking sleeping bag compartment. -Quite warm: I'm a cold sleeper, and I was definitely comfortable in 40 degrees. I also slept with it partially zipped in 60 degree nights which was comfortable. A nice touch is that you can unzip near your feet for some air if you get too toasty! -It's down! My first down sleeping bag. Great price considering that it's treated down. -Good fit: I am a 5'1", average weight, female. The regular size was plenty roomy. -The bright blue color is awesome. -Zips open on the right side... different. Negatives: -Tough zipper. All sleeping bags I've ever had have tricky zippers, this was no exception. It did appear the designers tried to improve the zipper functionality with a better zipper grip, but it constantly caught on the sleeping bag material so I worried about it tearing. -No cozy hand warmer on the inside of the sleeping bag. I love that feature on my zero degree bag, but i guess it's not that important on a warmer weather bag.

I am just shy of 5'7"........should I get the regular or long?

Asked by: SkiWV17
The regular will be fine for you. There is enough room in the hood area for you to lay on your back and not be touching the top of the bag.
