I have the Gore Windstopper Jacket. I just wore it for the first time this past weekend and I think it will work out perfectly as opposed to my PI Whisper jacket.
I got the Gore mainly for the zip off sleeves and then it turns into a vest. There are times when it begins chilly, and having the option to zip off the sleeves is great. There are also times when I just a vest would be perfect as opposed to a whole jacket.
It has good body, but not heavy at all. It is not the crinkly material that the PI Whisper is made of. My PI Whisper had no pockets either, which I missed. They have changed that since I bought it however.
Here is a link to the Gore....
