I have a fairly new REI Flash 65 that weighs 3lb, 3oz and is a pretty decent pack. I have my cold weather pack weight down to 26-27 (includes supplies for 4 days) pounds depending on what exactly I end up taking. I'm considering the purchase of the new Granite Gear Crown A.C. 60 when it becomes available. I believe it weighs 2lb, 2oz...is it worth $220 to save a pound?
