http://www.rei.com/product/811541/big-agnes-grouse-mountain-15-sleeping-bagI have one camping trip out with the Big Anges Grouse Mt +15 sleeping bag. I was sleeping in the back of my truck with the tailgate down, and there was frost in the am, don't know the exact temp, but I was cozy all night in my skivves.
The thing I like most about the bag is there is no isulation on the bottom half, but has a sleeve that is a perfect fit for a contoured pad, but will fit any standard size pad. With the pad securely under the bag I was not rolling off all night like I usually do. I definately slept better than I usually do in a sleeping bag. It seems fairly light if packing is your thing.
If you are in the market for a new bag, you might give this one a look.
