I wear Fox Attack Water pants for riding in the Pacific North-Wet. Although short in the leg (I believe the website said 31 inches & I wear 35 inches) the knee is exactly where it needs to be. So I can deal with that. The recently reviewed Club Ride may be an option as it is a little longer in the legs. One of the local blogs waxed lyrically about the Race Face Agent Pants for riding in this neighbourhood as well. And as many of the readers noted that again they were short for the leg length, Race Face is considering some longer lengths for their next production run.
We will have to see.
