Do any of you have any experience with the Predator Rut Series Waterproof Parka? I'm looking to basically consolidate my softshell jacket and lightweight rain jacket. I can't tell how heavy it is, nor if it's packable at all. My second option is keeping my current rain shell and replacing my softshell jacket with a lightweight puffy. It's a backpack hunt and I want to stay light but efficient. Last year I packed the shell and used the Predator Adrenaline jacket. To be honest, it wasn't enough when stationary on those cold mornings. It was the first week of season but I got cold several times.
