Not so sure of the waterproof capabilities, but other than my arms getting a little wet from the rain. I should have been dripping so I’d say 3/5on waterproof, the camo strips down the sleeeve is where my sweater was wet. I don’t have many complaints, it’s a very warm jacket. Up in the mitten state land inters can be brutal, but you honestly can’t feel the 20 degree winds!
