Ugh. So, after I got all your advise and pulled the trigger and got really excited, Dri Ducks did not work. I got them and put them on. I was pretty pumped. They were really comfortable and light. I took the jacket, rolled it up (gently as I had heard this jacket was delicate), and stored it in my backpack for a rainy day. I got one on the first day, as it rained when I got to work. I went to lunch walking maybe 100 m to a restaurant. I ate and walked back to work. On the way up the stairs, the jacket caught a loose bracket on the wall, and a inch hole ripped in the bottom. This was sad, but understandable. I knew it was delicate. That bracket would have ripped a lot of jackets (maybe not as much, but the others would have ripped). I can patch this hole with some duct tape and move on with my life. Also, this was <$20, so I can buy a new one. So then I take the jacket off and notice about 9 tiny holes in the right arm. On closer inspection, these holes are where the fabric creased when I rolled it up to put it in my backpack. Curses! I am too rough for this jacket. If it gets holes when I roll it up, I cannot take it where I will depend on it. I have donated this jacket away.
While I appreciate y'all's advice, it did not work out in this case. I am glad that the Dri Ducks work so well for y'all, but I am forced to look for something more durable. Back to the drawing board. Thanks for the help on this one; I hope y'all bear with me as I try to sort out new options.
