For cold weather bowhunting, several years ago I got a Predator camo shell coat and pants from Hidden Wolf. The material is soft, water & wind repellant and sized big enough to put as much warm clothing as I need under it. I can wear that outfit from leaf-off to January by varying the layers underneath. As far as scent-lock, I can't speak to it. I don't own any. I keep clean and hunt the wind.
