Rain-wind jacket and pants.

Hello,
my friend is going on a backpacking trip for his first time, we will be in RMNP late July.
He wants an outer layer protecting from rain-wind, and something preferably versatile, like 3 to 4 seasons.
I use OR top and Marmot bottom, they work fine to a degree, as most of them, they start loosing their proofing under heavy rain for prolonged period of rain time.
I would love to hear your suggestions, as I never went wrong with stuff I bought based on members suggestions here.
