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
  • Regular Wide size has a relaxed cut that offers more room to adjust your sleep position; Regular and Long sizes have a fitted shape for superior warmth to weight ratio
  • 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 5 out of 5 by from Very Comfortable Sleeping Bag I got this bag a fed weeks ago and was afraid to use it on our multiple day pack packing trip because it is early spring in northern Idaho. We still have snow in the higher elevation, but decided to take it anyway because it is such a great size to backpack with and it was wonderful the material is great and most important it kept me warm. I sleep cold so that was on the top of my priority list. I kept warm with very little clothing and no liner. I think it was 20 degrees and no problem the material is very comfortable and I did not feel the zipper at all.the zipper pull is amazing you can get to it easy and the bag does not get stuck in itt.

Rated 5 out of 5 by from LOVE that this bag is WATERPROOF! I love this bag! I live in the South so the temp rating wasn't really tested since it was 70 degrees overnight on my hike. BUT, it rained and I can say that this bag is a great waterproof bag! I stayed completely dry and even shoved my gear into the bag to keep it dry as well ( it wasn't supposed to rain, so I was completely unprepared). I've never owned a Women's bag before and didn't really see the point before but I can now see the reasoning for such a thing! It gives where it needs to give and fits where it needs to fit. I have all sons so they will NOT be using my new bag as they have in the past. I will be keeping this one all to myself!

Rated 5 out of 5 by from A great bag for larger ladies! Finally, a sleeping bag that accommodates larger ladies who want to go on outdoor adventures! I am 5'6", roughly 220 lbs, and somewhat broad-shouldered and large-hipped. All the women-specific bags I have previously tried have felt too constricting at the arms for a comfortable night's sleep, and the men's wide bags I have tried are all designed for men up to 6'6" - that's a lot of extra bag to carry, and a lot of excess space to fill on a cold night! This bag is the answer to what I have been looking for. I bought the Regular Right Wide model during a recent sale, and just took it out for a field test during a chilly, damp two-night backpacking trip. I had been worried that at 5'6", the max height range listed for the bag, it would feel too short for me, but the length turned out to be fine. I also found it perfectly roomy and comfortable at the shoulders and hips, allowing me to turn over during the night from side to side. Furthermore, the bag kept me warm enough; it got down to about 40 degrees at night, and while the bag was not immediately warm upon getting in, it did eventually keep me toasty in long underwear and a knit cap. (I have yet to test the 20 degree rating - I'm a little dubious it would be comfortable at that temperature, though a more insulating sleeping mat might help.) Finally, it was a great size to carry - with a compression sack, I got it down to the size of a volleyball. I'm so glad to see an extended-size option from REI, and I would recommend this bag in the Wide size to other women of a similar stature!

Rated 5 out of 5 by from Comfy and warm! I took this bag backpacking in the Sierras and temperature dropped to 37 F at night and I was very warm in the bag! I slept with a beanie and didn't need to zip my sleeping bag all the way since it was already nice and toasty. Compared to my other mummy sleeping bags, this bag had more room for me to move around and was comfortable to sleep in and I didn't feel claustrophobic. I'm 5'7" and went for the long version of the bag and it's a great fit. Another thing I really appreciate about the bag is the zipper, it's nice and big and makes it easy to zip without snapping on the bag! It's a great bag for the price!!

Rated 4 out of 5 by from Comfortable and lightweight So far this sleeping bag has been great. The fabric is very soft, the bag is lightweight and packs small for backpacking, and it is designed for a woman's body. The baffles are one of my favorite things about this bag. They keep you nice and toasty without having to cocoon yourself entirely. The only reason I can't give this 5 stars is because I haven't been able to test the temperature limits yet. I used it in 50 degree weather and was plenty comfortable without overheating. I will be doing a through hike in two months through the Sierras and I plan on taking this bag. I will write a more thorough review then.

Rated 4 out of 5 by from Great for Tall Ladies After using a Men's Regular for several years, I will never be going back. The Joule 21 Tall was perfect for my 5'11" frame. I had plenty for room to burrow down into the bag and I didn't realize how much I would appreciate the extra room in the hips. I took this bag out for a couple nights on the PCT in Montana. One night was very windy and dropped into the 20's. I was chilly at times, however this could have been partially due to poor tent placement/ setup. The second night, I was plenty warm even without my bag liner. This bag is perfect for backpacking, as it packs down small and is lightweight. I've already convinced one friend to buy this bag and she loves it as well.

Rated 5 out of 5 by from Quality, Durable Bag for the right price I used this bag for my backpacking guiding job and want to say a few things. If you are looking for a quality bag for around 200 bucks, this is it. I'm 5'6" and about 140 (give or take). I am very comfortable in the fitted bag. This bag is obviously not waterproof, but it is insanely water repellent. I slept in it under a bivy for a while, and the bivy either didn't do it it's job or the condensation was too much, either way, the outside lining of my bag would be completely damp and somehow retain loft and warmth. Women specific bags are where it's at. Extra warmth in the footbox, and shaped to your body/height is so useful. I never knew what I was missing by using men's sleeping bags, feeling like I was losing heat. Packs down super small, in the right stuff sack. Average weight for a down bag of similar temperature ratings. Seriously, buy it if you are thinking about it. To be aware of: Literal animals were used for the insulation of this bag, it will probably have a slight animal smell. That is just a fact of buying down bags.

Rated 5 out of 5 by from Warm & cozy Out of the stuff sack, this bag has incredible loft and provides a very comfortable night's sleep. Inside a compression sack, it packs down incredibly small. I took it to the Wenaha-Tucannon in May, where nighttime temperatures dipped into the upper 30s. Even my chronically frozen toes stayed warm. On a warm and humid June trip to the edge of the Salmo Priest, I stayed comfortable by keeping the bag partially unzipped. The interior fabric is silky soft. I haven't had it out in wet/rainy conditions yet, but it handles typical condensation buildup without losing any loft/warmth. This was my first time trying a long bag (I'm 5'8", 155 lbs) and I won't go back to regular. Great overall fit, and the ingenious zipper design means this is the first sleeping bag I've had where I haven't accidentally gotten the zipper stuck on the fabric.

Why is this bag more expensive than the Joule 30? This bag appears to be heavier than the Joule 30, but virtually the same temperature rating, packed size, etc. Is there something I'm missing?

Asked by: aj88
​The Joule 21 has more insulation (more down feathers) and is a warmer bag. This accounts for the Joule 21 being more expensive and heavier in weight.

Why does your video description describe this bag as "relaxed" where as the item description say it's a "Fitted" bag. Would this be a fitted or relaxed bag?

Asked by: Drewbleedsblue
We carry this sleeping bag in three sizes. The regular and long are fitted. The regular wide is relaxed.

I'm 5'6 and 130 lbs, would the Regular Right fit me comfortably and have some room to move around?

Asked by: mgc11
Based on your height, the regular is the best size choice for you. However, we are unable to use your weight to determine if you will have enough room to move around, so we recommend that you compare your body measurements to the shoulder girth and hip girth to determine if you will be comfortable in the bag.

I have the older version of the REI Igneo men's sleeping bag with a #5 zipper and was wanting to purchase the Joule from the same series but it has been discontinued. Will this Joule sleeping bag be compatible with mine? Wil it zip together with mine?

Asked by: Niccogio
​Yes, these sleeping bags will zip together.
