Comments about REI Radiant Down +20 Sleeping Bag:

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.

    Comments about REI Radiant Down +20 Sleeping 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!

      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.

      Comments about REI Radiant Down +20 Sleeping Bag:

      Basically 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.

        Can'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.

        I 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!

        Comments about REI Radiant Down +20 Sleeping Bag:

        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.

        First season of use completed with several trips in mild weather and I am very satisfied with this bag. It is very warm, and very roomy. I was looking first for a bag that was big enough and was intent on a Big Agnes, but tried this one out in the store on a whim and thought it had much more upper body space. I did notice that the zipper was a bit problematic, and this has proven true in use. A very fair trade of but why can't a fantastic bag be perfect by having a better zip?

        Comments about REI Radiant Down +20 Sleeping Bag:

        Just picked this up, being on sale for Labor day and a good deal.

        Won't go too overlapping into detail about the things everyone agrees on, it is comfy, roomy for it's type, quite warm (near sweaty with the side open on the PCT).

        THE BAD. Down leakage has been a major thing. Every time I've had to stuff-sack it, I'm greeted by a plumage of little down pieces everywhere, flying around, filling my tent, sticking to clothing. Not so fun. Hopefully this subsides, and soon. Should have taken a photo for reference.

        Other complaints, it needs a velcro or some method of keep the top of the zipper closed/secure.

        Also could definitely use a collar or whatever it's called, the flap the cradles your neck/head in from the face of the bag. I have that on my two-person Big Agnes and it's great.

        Also don't see why they don't include a little built in pillow sleeve. Sure, you can stick one under the bag, but if you like to have your hand under a pillow or 'graspy-ness' forget that. I use an Expan air pillow, which doesn't feel very nice on the skin, it gets sweaty/sticky, whereas the pillow compartment on my Big Agnes double adds no weight, is super easy, semi-free-floating, and has a great sleeping texture to rest your face against.

        I suppose all those BAD are making me re-think not getting the grouse mountain... REI sale you got me!

        Good bag overall however like everyone else, the zipper snags easily.

        I'm a thin guy - 145 lbs 5'8 and the bag had plenty of room. It was super comfortable too and kept me warm at night when the temperature reached the 40's.

        At first it was a bit chilly but after I cinched the top I was perfectly fine. I wore a tshirt and shorts to bed. I don't know if the bag would keep me fully warm at 20 degrees but I have yet to test it at that temperature. I know that I would definitely wear a sweatshirt/warm ups when it gets that low.
