  • High-quality 650-fill-power goose down is warm, lightweight and compressible
  • Relaxed fit from the shoulders to the hips increases comfort by providing ample space to move around
  • Exclusive REI Down Fill Calculator optimizes the amount of down per baffle for the most warmth with the least amount of down

  • Ripstop nylon shell resists water and abrasion; smooth taffeta lining is comfortable against your skin
  • Shell fabric is treated with a Durable Water Repellent finish to repel moisture and stains
  • Contoured hood, insulated full-face muffler and full-length draft tube with ground-level seams keep body heat in and cold air out
  • The REI Radiant +20°F down sleeping bag has an external chest pocket that stows your watch, glasses or other small essentials
  • Differentiated drawcords (1 round, 1 flat) let you adjust hood and neck easily in the dark
  • Full-length of zipper is backed by wide, antisnag binding tape
  • Any REI backpacking bag can be zipped to any other REI backpacking bag because of the consistent 63 in., No. 5, YKK zipper; women's bags zip on the right, men's on the left
  • Pad loops provide attachment points to keep your sleeping bag and pad together to avoid rolling off onto the cold ground (straps and sleeping pad sold separately)
  • Includes stuff sack and cotton storage bag
  • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags

REI Radiant Down +20 Sleeping Bagis rated4.4444out of5by9.
Rated5out of5byfromRoomy Sleeping Bag!Being 6'3" and having a very broad chest really limits the types of sleeping bags you can get. I was super happy with the Radiant bag by REI. I was able to change sleeping positions from back to sides to stomach quite easily without feeling like I had my movement limited. The bag definitely keeps me warm, and if I'm too warm, I just let the zipper down a bit to get a nice breeze :) The bag does leak down, but what down filled sleeping bag doesn't?

Rated5out of5byfromDid what it was suppose to do!Given the bag I had before was the REI Zen synthetic +0F that I bought last year as I was reading from many other reviews that REI comfort temps were a little off. While the Zen +0F was a good purchase, being synthetic, it was hard to carry, even with a compression bag and a 85 litre pack. So going with the new 2012 Radiant down was a good choice. Use - I normally go backpacking the 3 colder seasons (spring, fall and winter), so I was a little leary about getting the +20F bag since the times I've gone out were always at sub freezing temperatures (but never in rainy conditions). The conditions I was backpacking anything from frost on the ground to 8 inches of snow and the temperatures at night were around in the upper teens to the mid twenties F. If you need a bag to keep you warm for the long hauls, this is it. Last thing you want is a bag that doesnt keep you warm at night when all the firewood around is damp and you have very little chance to keep the fire running for long periods of time. At 5'8", I was able to fit well in the regular size. It still gave me enough room for me to put my hiking shoes inside the bottom of the bag to keep them warm overnight and I still had plenty of headroom in the hood. What I did miss from the Zen versus the Radiant is that the Zen had an exterior zipper compartment to put either a flashlight, cell phone, or eyeglass case handy on the outside. I had to resort to putting those items in the hood and it wasnt comfortable having something like tools or parts poking your head at night when you roll around. Shape - The bag isnt that tapered as most mummy style bags, and the shoulders are a little snug that I found it more comfortable to have my arms folded over my chest (I have a 40" chest) than along the sides of the bag. The hood was really roomy. There was plenty of leg room for anyone that likes to move their legs a lot to find a comfortable sleeping position. Insight - One thing I would suggest that since it's down, I would get a waterproof stuff sack. Overall I was happy with the bag and it's a definite keeper (use a liner to make it last longer). Overall, I was able to pack the Radiant in a 15L compression bag easily. It may have been possible to even cram it into a 10L stuff sack, I havent tried yet, but I'm thinking that it can. The Zen I had barely fits in a 20L stuff sack. It's a great bag to have if space is limited in a 65L bag or so. I'm happy to say the temperature rating on the bag did exactly what it did and i slept in a normal long sleeve shirt, hooded sweatshirt and pants. It was more than warm enough for me in those conditions. Value - Given the price, it may sound steep for a first-time or rookie packpacker, but if you find yourself hiking in the colder seasons, this is the bag to have for many years to come.

Rated5out of5byfromLove this bag!This bag is as advertised!! I used the bag in an Eno DoubleNest Hammock with an REI Camp Bed 2.5 sleeping pad (4.5 R value) for the first time this past week in a friends back yard after a bonfire. It got down to 28 degrees overnight and the air was quite moist. I was only wearing cotton pants, a long sleeve T and a fleece sweatshirt. I had to unzip the bag during the night due to being too warm. I awoke in the morning to find a covering of white frost over the top of my entire bag and hammock. The grass and bushes surrounding me were totally white. I was very impressed and am very happy with my purchase!

Rated4out of5byfromGreat for the price.I bought this for my son since we are preparing to do some sectional hiking on the AT. We did one overnighter with it so far. It packed small and light and kept him toasty even when the temperature dropped to about 45. I would say it fairs as well as my Marmot Helium so far.

Rated4out of5byfromA great bag for spring and fall campingBasically using this bag as an upgrade to a +40 bag that I've owned for a number of years. It's really warm, and at times can be a little too toasty. But I would rather be too hot than too cold, especially in the mornings. This bag does tend to drop a few feathers, and I notice them flying around in my tent. Not a big deal, but I'm watching it. Overall, this bag is great for three-season use, and I'm looking foward to my next adventure on the North Shore of Lake Superior.

Rated4out of5byfrombest bag ever ownedCan't say enough about this bag. Really. Bought specifically for camping in cool/damp conditions in AK,WA, and OR. First time used was in Kodiak, AK in early September and it performed excellently. Yes, it does leak a bit of down, but that's peanuts. No problems with the zipper if you just go slow, and use a finger to help keep the material away. Love this bag.

Rated5out of5byfromLove it so farI love it so far. I'm a 6'3" 300lb backpacker...suffice to say it's hard to find gear. I tried a Big Agnes Encampment and froze to death. This was only my second choice because of price. I traded the encampment in for this one and I love it so far. Very roomy for a big and tall guy. This is the only bag I've found that's both roomy and warm. I checked the zipper snag as a negative, but what zipper doesn't snag? Great bag from a great company. Keep it up!

Rated4out of5byfromX-Wide Version is wonderful!I'm 5'11, weigh 200+ pounds... I am barrel chested and have large shoulders. Most "lightweight mummy" bags... well they make me feel like i'm in a straight jacket. I'm also a belly sleeper. I searched far and wide for a sleeping bag that would not only be light, but also large enough that I wouldn't feel like I was back in my mothers womb. I found this bag in the X WIDE format... and it is the most comfortable mummy bag i've ever experienced. I highly recommend this bag for those of you that are a bit larger than the average scrawny hiker. The extra pound or so it weighs over a regular sized ultralight bag, is worth it to me. Not everyone will agree of course. Have yet to test it in truly cold weather, but I imagine it'll do fine around 40+. I'm doubting it at 20 degrees... but time will tell.
