Are they telling you to bring waders? hip boots? other?
Did a hunt all in waders. Miserable. This last hunt I took my regular mountain hunting boots and then packed wiggys slip on wader things that I just threw on when needed. Made my hunt wayyy more enjoyable. Then again I only needed them a few times a day. Besides that, some good rain gear that you can put on easily over pants/boots. I used Kuiu yukon jacket and pants and it worked out perfectly for me.
