Hi everyone, I'm new here and this is my second season hunting.
I do not use a tree stand instead I Still hunt and Stalk. Here are my questions:

1. Can anyone recommend a good poncho or raincoat to go over my jacket and hood? One that won't leak through no matter how much rain comes down. I am leaning toward a poncho because that is what soldiers are equipped with.
   
2. Has anyone used these waterproof bibs in extremely rainy conditions? I am hoping I can sit down on wet rocks and branches all day without getting wet in them too.
   
3. Has anyone been caught out in the rain or sat in wet conditions in these coveralls?
   
4. How the hell do you take a crap in coveralls?

Thanks and if anyone is confused or interested I have two sets of gear I plan on wearing depending on the temperature.
Moderately Cold Gear - Bibs + Jacket with a poncho in the pack
Very Cold Gear - Coveralls with a poncho in the pack just in case.
I am going to carry additional layers with each set.
A Fleece, long sleeve thermal, thermal long johns and my base layer is a t-shirt.
All layers are polyester!
I made the mistake of wearing Cotton, Cotton, and a bit more Cotton last year.
