I think that you must have clothes with more than 70 warmth (or some amount like this) to stay dry. It works for me with cloak on my usual clothes (trenchcoat, cargo pants, kevlar vest, 2 and half million backpacks, army helmet, metal guards and god knows what else I wear).
As far as I know the clothes that are rain resistant are the rain coat, poncho, and trench coat. There are /probably/ other out there, but I am not sure. I have not heard of the 35 warmth thing before.
One of the more disturbing, or interesting depending on your outlook, instances involving wolf suits is that time I was harassing a school and throughout the residential area immediately surround the school were wolf suits. Wolf suits in almost every single homestead. It’s as if the parents are involved in some sort of local club and go have some furry parties when their kids are at the nearby school or late at night.
