RE: changing before or after you leave for your stand
I wear scent free base layers that are washed regularly, I change at the stand before and after the hunt.It works well for me as I am a big guy and I dont need to wory about getting sweat up on the walk in most of the time. I also do it to avoid rubbing the carbon out of my suit liner by too much motion. If I am stillhunting, then i wear different garments.
