I went shopping for a rain layer today. Walking around wal*mart with the honda joe rocket gear got some looks.
Considered the frog toggs pvc for $30, but the seam stiching looked suspect. The river frogg jacket didn't pass the wet thumb test. Soaked it right up.
Ended up getting a new pair of leather boots for less than the froggs. Those got a sno-coat treatment as soon as they were home.
Since Goodwill was nearby, I stopped in. Just in case someone had donated a rain coat. They did, just not a size large enough for me + armor.
What I did come up with was a waterproof sweater! A thermal insulated waterproof underlay is better than nothin. $7 for a last line of defense. Should the can of kiwi camp dry I hosed the rocket gear with, fail.
I've had a pair of really solid rain pants since I was a teenager. Used em during bicycle commuting, in pretty serious rains, and they work good. I think they're helly-tech. Been a while since I read the tag. Despite the added girth over the past few years, they do fit over the riding jeans.
Those got a healthy dose of camp dry as well.
