I've yet to encounter any leakage issues with my Percip, but I'll keep an eye on it to see if this rings true. I've had the thing for almost ten years now and it's gotten me through some nice rainstorms. However, I do need to confess that I follow a system kind of like Lori's: for winter, hard-weather, or snow outings, I have an REI Elements jacket that covers me then. It's heavier than I'd like, but offers fantastic water resistance and a nice wicking layer to help ward off clamminess.

I also must agree full-heartedly with the sentiment that rain gear isn't to keep you truly "dry" but drier and less miserable than you could be.
