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 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 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 The Prom Dress While it looks like a lovely taffeta burgundy prom dress, this bag is light weight, warm and comfortable. Great for backpacking. My neighbor bought one like it two weeks later.

Can a compression sack be used for this sleeping bag?

Asked by: KSML
​Yes, the Joule can be compressed. Choose a compression stuff sack about 8” x 18”/ 12 liters. https://www.rei.com/c/sleeping-bag-accessories

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.
