Comments about Big Agnes Lost Ranger +15 Sleeping Bag - Long:
At 6'2, 245, I have broad shoulders. I had a great March night in the mountains at temperatures in the 30's. Although I haven't tested this bags temperature rating, this is definitely a bag for a big guy. I slept like a dream on the ultra comfortable Big Agnes sleeping pad. I absolutely love the Big Agnes system since you can roll around and never slip and experience ultra comfort throughout the night. I love love love this bag.

After reading great reviews of this bag on the net, and climbing into it in the store several times, I decided it was the bag for me. I've taken it on several trips now and will be returning the bag. Why? Of the 8 nights I slept in the bag, in combination with the Big Agnes insulated sleeping pad, I was cold 7 nights. 3 of those nights I was too cold to continue sleeping. The proverbial straw that broke this camel's back was this last trip I was wearing every piece of clothing I had with me, buried myself deep into the bag, had a sleeping bag liner, and woke up at 2:00 am too cold to sleep. I am not a cold sleeper either. I usually peel away layers throughout the night with other sleep systems.This bag is not all negatives though. A few things I really liked about this bag were: it compresses small; the sleeping pad system design is very convenient for us back-sleepers(this would be a negative if you sleep on your side); it is extremely wide in the shoulder and waist areas, I did not want for more space inside this bag; finally, the price was right, had it kept me warm. I purchased the '07 model [...], however, I'm still returning it because a cold bag does me no good, no matter how cheap.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag - Long:
I have always had a tough time getting to sleep while camping and wake up with sore spots that last all morning. In a mummy bag I have had a few nights just staring at the roof of my tent until dawn. I have only spent one night in this bag and I am wondering why I need a bed in my house! It's like when I was a kid and built a pillow fort. You have to try it. Go to the store, make then set it up with the REM Big Agnes pad, roll on to your side (YES you heard me) and just dig it. Your hip doesn't hit the floor, the bag lets you move around with out making you feel like you are rolled up in a rug. Can't wait to get out there knowing that every night i will get the rest I need to hit the trail the next day.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag - Long:
First of all, it's a great bag. But remember for every "pro" there is an equal amount of "con".
I'm 6 foot, and 180 lbs... and once it gets below 35 degrees, I can't keep this bag warm. It's just too much space to heat up. Every time I move inside the bag, I get cold. I camp at least one weekend a month,and got this bag in May...it did great up until Late October. I chose this bag because I move around a lot at night, switching side to side, and the extra room makes that possible... but once it gets cold, you have top cinch up the top or you loose a lot of heat out of that same "spacious" opening, and with a cinched top you are limited to sleeping on your back. The integrated pat is also a mixed bag... It's great to move around at night and not slide off your pad, especially when the ground isn't perfectly level (which it never is). But when the pad is integrated, the sleeping bag is, for all intense and purposes, rigid. You really can't sit up while in your bag to get dressed, or undressed, without unzipping and getting out of the bag. And for some of us side-sleepers, the fetal position is possible in a tight mummy bag because the whole bag can be turned on it's side... once this pad is integrated, you aren't sleeping on your side unless you're willing to partially unzip the bag. I can camp all year and maybe only spend one or two nights in weather that is below 15 degrees... I was hoping this bag would get me through more than just 3 seasons, but it won't, in fact it's not even getting me through 3 full seasons without the extra use of fleece underwear.

I love this bag. I used it to hike the southern half of the Appalachian Trail last year from October to December. It got down to 10 degrees in the smokeys and with my long underwear and coolmax bagliner I was plenty warm. I'm a little shocked that some reviews claim its not warm enough. I had very little body fat at the time and was able to stay warm. I'm 6'3 and I was able to slip down inside and cover up my head. I also loved the sleeping pad pouch. You never slip off. This was my favorite piece of gear during that hike! MuffinMan ME-GA '08

I use this bag for backpacking and car camping from early spring through late fall. I intend to pair it with a light outer bag for winter use.
I bought this bag after a lot of research. It was the ONLY bag I found that was large enough for comfort, yet light enough for backpacking. It is unique in that sense. I know of no other rectangular bag that is under 3 pounds and rated to 15 degrees.
I disagree with the comments that this bag isn't correctly rated for temperature. I'm a cold sleeper. I've had the BA Lost Ranger in 25 degrees with light clothing and an uninsulated air mattress. I believe it would work at 15 degrees as rated if you wear thermal clothing, a fleece jacket, light mittens, and a hat and use an insulated sleeping pad. Sleeping bag ratings assume that you ARE dressed like that, not in your boxer shorts and t-shirt.
I LOVE the size of this bag. It's great to be able to change positions and stretch a bit. It is far more comfortable than a mummy bag, especially for larger folks or those with arthritis who can't be cooped up in a small mummy.
My one problem is not with this specific bag, but with the whole Big Agnes concept of not having insulation on the bottom and inserting the pad in the bag. As other reviewers have noted, that creates a rigid bag that works best for back sleepers. For side sleepers---and I think there are many side sleepers---the bag is stretched too tightly over the shoulders and feels weird.
More seriously, this set-up prevents you from drawing the bag close to you because it is held rigidly by the pad. The result is loss of warmth.
I don't put my pad in the bag. I just put the bag on top of the pad. That works fine as long as you make sure on a cold night that the uninsulated part is UNDER you, not at your back, e.g. when you turn over. With a bag that's insulated top and bottom you don't have to worry about any exposed body parts.
Don't hesitate to put the bag on top of the pad. It is perfectly useable that way. You don't HAVE to put the pad in the bag.
The big advantage of the uninsulated bottom is light weight, and the Big Agnes bags do achieve this very well.
Bottom line for me: I'm very satisfied with this bag after learning to work with its quirks. It is light, warm, comfortable, and highly compressible, and those are the most important criteria for me. On top of that, the price is reasonable for the quality.
NOTE ON SIZING: The BA women's bags are noticeably narrower. If you are a larger woman go with a man's bag like the Lost Ranger.

Finally, a light weight mummy bag that doesn't make you feel like you're strapped into a straight jacket (especially if you are a bigger guy - e.g. 6'0"+ and/or 200+ pounds)!!! This bag is awesome! It is built wider in the hips and shoulders to give more room for those who aren't exactly comfortable with the traditional mummy bags. If you're over 5'9", get the long bag. I used it on a recent 4 day/3 night hike in the Sierra's where temps got down into the upper 30s each night and it kept me toasty (I actually had to unzip the bag in the middle of the night to cool down). The shoulder baffle kept the heat in and the cold out.
The integrated pad is genius (it's a "must have" if you buy this bag). A little thicker than my ThermaRest pad, so it gave me more cushion, while providing the insulation needed from the cold ground without the added weight. Also, no more rolling off the pad during the night as I move around, since it's integrated into the bag itself. I've NEVER slept this comfortable in the outdoors in 25+ years of hiking/camping!!!
The only possible downside is that the zipper is a little fussy, but it's not as big of an issue as others have made in some of the other reviews.
Buy this bag if you want a light weight, roomy, warm, comfortable sleeping bag for backpacking!

It claims to be 15 degree bag, but there is no way I can use it under 40 degrees. Comparing to my wife's Marmort this product is completely misleading!

Bought this sleeping bag looking for comfort, turned out very comfortable. One thing though is that you get cold. When snow backpacking, even with a hand warmer in their, still cold. need atleast three layers to stay warm. Still definetly recommend for comfort and stuffs very small

Comments about Big Agnes Lost Ranger +15 Sleeping Bag - Long:
I'm 5'10", 155# male. Bought Big Agnes after feeling trapped in narrow mummy bag. I love the wide body and the pad system. I use it with Big Agnus thermal pad.
Regarding temperature: for me bag work in temperatures down to 30 degrees especially with full amount of down (see below). And I sleep outside without a tent if it's not raining.
The Lost Ranger is wide enough to allow me to sleep on my side and wrap my arms around a pillow. I like a lot of other features, like the built-in pocket for stuffing clothes to make a pillow. Also the contoured shoulder/collar down stuffed part.
My only complaint--and it's a major one--is the lining ripped on me. Starting on my first trip (June/July '08 Olympic National Park). I noticed down feathers clinging to the sleeping pad when it was removed from the sleeve. I ignored the problem and went on 2nd trip Aug '08 to Eastern Sierras/Alpine County. Kept loosing down whenever pad was removed.
3rd trip-Big Bend National Park last Thanksgiving. Spent one night up in the Chisos mountains where the temperature dropped below 32 and felt cold for first time--was wearing thermal underwear, wool cap and inside a tent. I was able to sleep, just not comfortably. Other campers reported being cold also. By then my bag had lost a lot of down.
I finally returned it to REI for a replacement bag. The lining inside the thermal pad sleeve was torn along the seams in at least two spots. I'm hoping the weak seams were one-time problem with my first bag and not a design flaw. I haven't used the replacement yet to test.
