Big Agnes Encampment Sleeping Bagis rated4.05out of5by20.
Rated4out of5byfrom15F rating is stretching it a littleI've been using the Big Agnes Encampment 15 for about 8 months now. I like it a lot. As with any sleeping bag temp rating, I feel the ratings are for survivability, not comfort. I consider myself a cold sleeper and this is a very good 30F bag for me. Took off with some friends on New Years Eve in western NC for a one night stay with the temps in the mid 20's. I sleep in thin silk weight thermals and decent wool socks in the winter months on the trail. I did have to add a Therm-A-Rest tech blanket to the mix to get in my comfort zone with this bag with the temps mentioned above. But that is what I was expecting from this bag. Combined with the Big Agnes Q-Core SL Sleeping Pad this is one nice, lightweight, affordable sleeping system.

Rated3out of5byfromNot a 15 degree bagWanted to go backpacking in snow so bought this bag with 15 degree rating. Packed well enough for me and was roomy. Trouble though, I froze the entire 2 nights. This bag only has insulation on top and sides because you need a pad with it. Even with a pad, its not even close to a 30 degrees bag!

Rated5out of5byfromI finallyI seriously have owned over a dozen bags. My greatest challenge has been the restrictive style of most mummy bags. A couple years back I finally found one with "leg room"...but it is almost 8 lbs...way too much for backpacking! The other challenge has been slip-sliding away...right off the sleeping pad. The BA Encampment addresses all my is almost as though it was custom made just for I need a shorter one for my dog!

Rated5out of5byfromnice looking not well madeI have only used it once but it kept me warm and dry, even as the temp dropped and the condensation rose. it worked well and served its needs.

Rated3out of5byfromAdequateI took the bag backing and got a little cold when the temp was in the high 30's. I expected it to be warmer with the +15 rating. I do get colder than most though. Side to side, it's very roomy which is great. It's hard to curl up on your side though since your pad is inserted into the underside of the bag. Length for the "long" is normal -- I'm 6'6" and did not have any spare room at the top or bottom of the bag. And this has more to do with the mat, but when ever i shifted positions, the fact that you are directly on top of the mat makes the volume of noise caused by the friction to be louder than normal

Rated5out of5byfromLove this bag!Bought this bag and the pad to replace my old set. Used it the first time on a back country trip. It set up easy,was warm enough to sleep commando style. Loads of room! I could side sleep in the thing no problems. The only real complaint is that where the insulation ends and the pad pocket begins it tends to lose heat or let cool air in. definitely a 3 season only bag and for use in 30 degree + conditions.

Rated5out of5byfromWinter be DarnedI ran into someone on the trail that had the Big Agnes Lost Ranger and I was thoroughly impressed with the sleep system. I opted for the Encampment because I like having more space for my legs and to roll around and also to keep clothing that may be a little damp so I can dry them or keep them warm for the next morning. The bag packs down very well. I have an REI 21 liter compression sack that can get the Long version of this bag down small enough to easily fit in a sleeping bag compartment with spare room. This thing has been wet after a night of heavy rain and dried very quickly. The inside is very plush and extremely warm. I love that it has a sleeve that keeps an air mattress in place.
