Big Agnes Lost Ranger +15 Sleeping Bag - 2011 Closeoutis rated3.6364out of5by11.
Rated1out of5byfromWell made: I froze at 30 degrees.I was very excited when I saw this sleeping bag on sale. I was going to buy the Encampment (synthetic version) and was psyched to see this down bag. Firstly I love the concept of an insulated sleeping pad; make sure you get one that is properly insulated to the correct temp rating. We were in mild-spring conditions (mid 30's-high 20's) in a BA Tent. There was little wind and I was on a 15 degree pad also. I found there was adequate space...but hard to zip up because of the configuration. I noticed that I had cold spots almost immediately. I wore a heavy base top and bottom, wool sock and a hat. There was a cold spot all along the right side (op of zipper). I grabbed a polar fleece and put it along my back. I did sleep a little but each time woke up shivering so hard that it was commical! I eventual put the polar fleece on and was still freezing. At 2:30 I went to the car, grabbed the stove and made decaf tea in order to warm was only 28 degrees! I wanted to love Big Agnus but sent her packing when I got back into town...looking towards Marmot or TNF next time.

Rated4out of5byfromLight and compact, but note the design!Just note that as with all Big Agnes bags of this design, you must use this with a pad that supplies the otherwise absent lower insulation. This pad must fit the size of the pocket in the bag for it.

Rated5out of5byfromIts Great!I used this bag on a backpacking trip. It worked great. My sleeping pad ended up having a hole in it so I was pretty much sleeping on the ground. So the whole no padding on the bottom was the pits. BUT I really didn't get too cold. It Hit about 25 so considering I didn't have any pad on the bottom I think the sleeping bag did its job. Cant wait for more trips to use it. Definitely have recommended this to a few people already!

Rated5out of5byfromGreat bag for those who like extra roomNice and roomy. Like how the pad slides into the bottom of the bag, so you never wake up off of it.

Rated2out of5byfromGood Bag but not for me.Ultimately went with this bag off a recommendation. I am 6'1" and was talked into the long. I already own the Big Agnes pad that matched this bag so deciding to buy this bag was a fit. Long story short after laying on the floor in the basement of my house with the pad inflated and the bag zipped I found myself shivering cold. The temp rating is completely off base and to even get close to calling this a 20 degree bag would require a hefty fleece liner. I weigh in at about 210lbs and thought that the long would allow more comfort but what I didn't realize was the added width that comes with the long version. This added width just made it so that my arms simply fell of the pad and hit the ground and this added to my coldness. This bag still had good feel to it while inside but would only be good for warm summer car camping.

Rated5out of5byfromAwesomeA great bag! Roomy and warm. Ive had a hard time sleeping after hiking all day in the past, because I couldn't get cozy, but the first time out with this bag, I didn't wake up every two hours and cry, I actually slept!

Rated3out of5byfromNot good for cold weatherIm currently hiking the AT so i am relying on my gear on a day to day bassis, i now seem to realise even the slightes problems with gear items. I enjoy the ablitly to slip my sleeping bad into the compartment on the bottum of the bag which helps to stay on the pad through the night. I do not howerver like the lack of warmth this bag has. Ive had days of 0 degrees to days of 70 degrees and this bag is comfortable in about 35 to 40 which i would expect comfort of a 15 degree bag to be a little lower in the temperature range.

Rated4out of5byfromGreat bagI bought this bag mainly due to its shape and temperature rating - I wanted a bag that I could stuff another sleeping bag inside for winter camping, without having to spend a lot on a bag with good low temperature rating. As a side note, this bag does require (suggests) the Big Agnes sleeping pad to tuck into a sleeve on the bottom of the bag; there is no insulation on the bottom to reduce weight. I already owned the Big Agnes Insulated Air Core so that worked out pretty well. A few friends and I went winter camping in northern MN this winter with overnight temps ranging from 0-10 degrees at night. I stuffed my Marmot Cloudbreak 32 (synthetic) inside the Lost Ranger (down), and while wearing a lightweight base layer was completely warm. No cold spots etc. The bags fit perfectly together and I didn't feel constricted. I could roll around in the Marmot and the Lost Ranger stayed flat due to the internal sleeping pad which was extra nice. I've read several other reviews that say this bag's temp rating is inaccurately low, and I've not tested it on its own. Two bags though = awesome.
