This bag is the best of what I was looking for.

I wanted a synthetic bag, because down is got only by plucking live birds or killing them...something I wasnt ready to sacrifice for lighter weight

So then I was in a tough situation, because synth bags are known for bulk and weight. The staff at backcountry.com helped me find this.

The longest bag is very warm when paired with the 15* diversion sleeping pad and it packs down to about 12 by 8 inches in a stuff sack (you will need a compression sack to compress it down to a manageable size).

For its degree rating and quality, it was the smallest pack and wieght size I could find, exactly what I wanted.

There is almost enough room in one to fit a cozy couple, and when my girl got a matching bag to zip into mine, we had more room than we thought we could for camping.

Im stoked with this bag.

Good ol American ingenuity at work here. No sliding off the pad in the middle of the night. (Where is there a level piece of ground out on the trail?). I have the air mattress from 3 years ago, and I think the temp rating on the new one is better than the one I have. My first experience in cold weather was, shall I say, COLD! Next trip I brought an emergency space bag and slid the mattress into it. Man, that did the trick! The space bag is only a few ounces, but it sure keeps the heat in. I have the long version, and it is really too big for me (I'm 6 ft.) It does take a little time to warm up that much space inside. The weight is a little more than I like for long backpacking trips, especially with the air mattress. Probably best for an occasional overnighter where weight isn't so critical. Very comfy bag. Well made, zippers are great, ready for years of camping.

I LOVE my encampment, and it's been so good to me. I'm a restless sleeper and the sleeve system and roomy back are great.

However, the roominess can keep you colder (more space that you have to heat), and if you don't get the insulated pad, the bag WILL NOT keep you warm down to its 15 degree rating. (This can be remedied with a silk blanket though.)

Had this bag for a little over 2 years now. Used it multiple times in 3 season camping in western parts of Virginia. Very comfortable and very warm bag. Used it in temps down to 22 degrees and stayed very warm. Would recommend for a friend to buy.

This was my first "real" sleeping bag. I'd never liked mummy sacks and I always slid off of my pads and bruised my ankle bones. After a lot of consideration and many naps in demo bags, I decided that the big agnes system was for me. I can't take it anywhere without someone commenting on how cool it is that the pad goes into the bag. I bought a cross mtn too for summer and layering. I've used it for both and loved it. I got my sister and her husband and my girlfriend these same setups for XBox last year and they all love them. Hi Ya!

I bought this bag in a big hurry AND because my son bought me one of the Big Agnes sleeping mat that fits into the bag for my birthday. I should have bought the down bag (in my haste to buy I thought that I did). We camped in the Boundry Waters and it was around 30 degrees at night and I was very cold! I thought that maybe is had been packed for so long that it needed to be left out for a while, so I did in hopes to to get the stuffing to expand. When I returned home I put it into the dryer with some tennis balls and have yet to try it again. I will say that it is made incredibly well and the bag/mat combination is just great, no more turning and falling off the sleeping mat because it fits inside the bag. I really want to like this bag, but again I probably should have bought a Big Agnes down one!
