Great bag
I like the width of this bag and find it much easier to sleep in - especially at the knees and the feet. In general I think the Big Agnes system is great. I do think their temp ratings are slightly low. For example I think the 0 degree Storm King feels more like a 15 degree bag. I've slept in it down to 20 and wouldn't push it much beyond that without a liner or more clothing.
