Check out Costco's website for bags. They have a couple. I still use my Woods 5 Star rated bag. I have been using this bag since I was a kid and it was my Dad's before that, and I am not a spring chicken anymore. I always slept the furthest away from the stove in the walltent, and I cannot recall the last time I have slept in the bag with the zipper done up, and that included sleeping in the tent while sledding in the mountains during the winter.
I too am looking at new bags, just something now a little lighter...Looked at the bags at Cabelas online: Browning McKinley -rectangle bag or the Cabelas 3D. I will make a decision this winter and buy for next fall.
