Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

While I haven't used this in anything too extreme yet it has seen a number of nights into the uppper twenties. It had a lot of warmth left to give at that temperature. I like the compact form when packing but with roominess in the legs & waist area. The lack of 360 degree insullation sounded much odder than it turned out to be. I didn't really even notice the lack of insulation on the back, and I haven't even added the proper sleeping pad that fits into the built-in sleeve just yet. I imagine it will get even better when I do that.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

It seems in an effort to cut weight manufactures have reduced the size of the typical mummy bag, and I found that I felt like I was being swaddled in one. Because of this I decided to try Big Agnes. I've used this bag on several week long trips, and it is very comfortable. It is large enough to that I can sleep on my stomach, roll over, and cross my legs inside of it. The tradeoff of course is weight. But it's worth an extra 8 oz. to get a good night's sleep.

I really like the Big Agnes sleep system. The integrated pad is a nice feature. (Make sure you buy an insulated Big Agnes pad (sold separately) to use with this bag.) The pad is so thick that you can set up over a rock or a root and not even feel it. It lowers the threshold for a suitable tent site and makes setting up camp a lot quicker.

The one word of caution I have about this bag, or any Big Agnes bag is that Big Agnes is very optimistic with their temperature ratings. This is not a 15 degree bag unless you are wearing a base layer and a hat. For me, this bag is comfortable to about 28 degrees. Below that it is going to be a very cold night. Your results may vary.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

I bought this bag to use in place of my mummy bag when car camping. I found the bag innovative in its use of an integrated air mattress sleeve on the bottom of the bag (I bought a Big Agnes air pad). This feature was very well liked, as it was 1) very comfortable to sleep on, and 2) prevented the bag from getting twisted (I'm a restless sleeper). However, the bag was not as roomy as I was expecting. I sleep on my side and found this position really pushed the limit of the bag (I DO have a 38" waist, so there's that to consider). When sleeping on my side, the bag was stretched taut and was pretty uncomfortable. I would prefer to have another 2" or 3" of room in the bag. Additionally, although rated at +15, this bag felt very cold at +25, especially around the feet (perhaps due to the extra room). I ended up sleeping with some extra clothes stuffed into the foot area of the bag. I would not consider this bag if you regularly sleep in your tent in weather below +30. Overall, this bag is a decent option for cool/fair weather car camping, and for those who are somewhat smaller in the waist than myself.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

I liked everything about it, even the fact you have to put a pad in it to insulate the back. No problems with itchy seams and warm but not hot. But, make sure you get a good pad. The inflatable one the REI employee recommended with it seemed to make me want to roll to one side or the other. Also, if I'm being picky, the zipper is a bit slow and may be prone to snagging in time, but not bad enough to keep me from liking the bag overall.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

This bag is like sleeping in a bed! I no longer slide around my tent since the pocket of the bag keeps the mattress in place. I could curl up with my legs at almost 90 degress (I'm 5'7"). The pocket for the pillow kept my clothes from coming unravelled and cushie for my head and there is a fluffy quilt part to the neck which felt like a comforter. I slept sooo well, I really felt that I was in my own bed.

not so great for side sleeping

Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

I tried this for only a half hour at home and knew I would have to take it back. The rating is what it would rate for me. I have to sleep on my side (apnea) and there is not really enough room in this bag to do that. Since the bottom of the bag has no insulation and depends on the inserted mat, the bag will not turn with you when you roll onto your side so you are basically trying to make a triangle out of the bag with the mat being the bottom of the triangle and your upper shoulder being the apex. Understandably, there is not enough bag to do this comfortably. If you are not a side sleeper then this is likely not an issue and you should ignore this rating - if you ARE a side-sleeper you better put a pad in it before trying it out at the store.

My partner and I opted for the King Solomon (also by Big Agnes with the pad insert system) double instead of two Lost Rangers. For the first 3-day trip at least we found it to be fantastic.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

I love Big Agnes Products. I just got done with a 5 day back country outting, which motivated me to write this review. I was disappointed with how inconvienent it was to insert the sleeping pad in small spaces. I was backpacking in the rain and had a 2 person tent to try to insert the pad into a Long Lost Ranger bag with another peron in the tent. I shurgged off the reviews of the zipper snagging until I woke up in the middle of the night trying to get out of the bag, just about kicked my way out of the bag!Another thought, I wanted a quick setup, so I didn't install the pad "bad idea" it's only insulated on one side not comfortable at all. This bag would be good for car camping not back country. Disappointed.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

I have no issues with this bag so far. I really love the room in it. I have only used it down to about 40 degrees so far, and I have yet to zip it all the way up so it seems warm to me. I am able to sleep on my side in the bag with the pad under me but I can see where that might cause some issues as the temperature gets colder because it does not create a tight seal.

I am converting to hammock camping and I think this will be a perfect bag for that.

Comments about Big Agnes Lost Ranger +15 Sleeping Bag:

I used this bag for one season. The first trip I took it on was a moderately cold one in mid March. However still within its temp rating; it preformed well. I used it over the summer and had no complaints, sort of light and it compresses well for 650 fill. By the fall I noticed that the bag was not keeping me warm. Winter passed and the heavier bags came out and then went back in the closet. Finally just over a year after I bought it; this April I slept on Isolation and i was cold it was only 35 degrees and my friend was warm in an REI Halo. Not cool, so I gave the bag a good looking over, and noticed the down had left the chest area and fallen down to the sides leaving only a double layer of nylon. I always store sleeping bags in large cloth sacks and I had never washed it. Not cool Big Agnes... Not cool. I returned it got a Sub Kilo on clearance.
