I pulled my Rain Suede rain gear from Cabellas the other day out of the gearbag I had put in my truck.Damn mouse had gotten in and chewed a big hole in butt of pants and collar of jacket.10 yrs on them.Light , durable,fairly quiet.
Might look at something different now, heavier/duty, quieter.Not much is really quiet when wet,but rain does provide cover sound.
Just cannot see paying $250 for rain pants....
