toasty and roomy
I took The Big A camping in the south in September so it wasn't quite cold enough for it yet but it handled the HIGH humidity really well. The zipper doesn't extend to the foot of the bag (which I prefer). Plenty of room for your head and shoulders, especially if you toss and turn a lot. And there's this extra cushioning pad at your head but on the top inside of the bag which was nice to wrap up in. Used a silk liner and slept in that with the bag mostly unzipped and was really comfy. Packed well in my stuff sack too (I didn't bring the airpad).
