First of all, I have rain parkas that weigh 2.5 lbs., 1.5 lbs., 1.0 lb., and 8 oz. What I was looking for was something lighter. I ran across the AGG rain jacket a couple of months ago. After I gave it some thought, I returned to the web site to make an online purchase, but there was no availability by then. I gave it more thought and decided to make my own. The first one was a snug Medium in sil-nylon and came out at 3 oz. However, that was my training, so I made a second one in Pertex, a shade larger, and it came out at 4 oz. I was satisfied with that, and the ladies were amazed that a guy could make anything like that with new sewing machine. Shortly later, AGG got their product available again, so I ordered a Medium (aware that they run large). The Medium was very roomy for me, and it weighs 4 oz. The workmanship is impeccable. So, I might wear the fancy AGG one around town, and I might wear my own Pertex one in the mountains. I am NOT a poncho guy.
