I've always really liked the Planks Yeti-Hunter Bibs. They moved to a new factory this year and they are definitely improved for this season. I've never had any issue with water getting in, in fact, I stayed dry in sideways Scottish rain in them a couple of years back which is about as wet as it gets. And I love the full zip legs because it means I can get at my knee brace to adjust it without taking any gear off. I don't know if they still distribute in North America though.
