I got this jacket and the next weekend i went out backpacking, and it rained and rained, i kept dry, some others in my group didn't, i felt pretty comfortable in it and whenever else i use it it breezes really nicel, very lightweight and compactable. the only down side is that it is a lightweight material, that you do worry about the durabilty of it. under a lightwieght (20-25) pound pack it performed nicely, though i was a little worried about the wieght of the back pushing the rain water through, do to the review by psisquared100135302, but i'm pretty sure the paclite would be fine for lightweigt to medium weight backpack, and the guy at goretex was just trying to sell a more expensive fabric, that would be less likely to be returned for repairs in the future.
