Waterproof and light weight? No such thing.
In your experience what makes lightweight hardshells not waterproof?
Waterproof means rubber!
Breathable means the fabric can release moisture. Which in turn means pressure can and will push water through the fabric. I don't know about you, but I hunt with a pack most of the time. I hunt in brush. I sit down and glass. I have slings on my guns. All of which rub and push water through the fabric.
