RE: Back country hunts and boots!!
I have a pair of the Danner Pronghorn 800 grams. I liked them so well both of my brother in laws went out and bought them a pair. They are very comfortable, light weight and they will keep your feet warm as long as it isn't unbearably cold. If you are going hunting with lots of snow and below 20's temp I would consider the 1000+ gram boots.
My .02 cents.
