The North Face Cat's Meow Expander

I tried it out early last spring and must say that it did its job pretty well below 30 degrees. Temperature dropped below 30 and still felt pretty comfortable with only a T-shirt and sweatpants.

The expander feature gave me enough room to move around and feel less cramped then most normal sleeping bags. I have broad shoulders and have always found it hard to fit inside mummy style bags, but the expander made it possible since it increased the girth by another 6 inches or more.

Hope this bag will last for awhile. My first TNF bag, previous ones have included REI, SD, and Mountain Hardware. Wouldn't recommend this for summer use at all, may get too warm. Compressability is awesome. Got the bag compressed close to the compression size of an equal degree down bag. Highly recommend the Cat's Meow Expander.
