I got some bison waders a couple of years ago, they get a little sweaty if you are working hard weeding or anything, but I don't tend to wear them for long periods so they do the job fine, I went up a shoe size seems to be the rule I think,
I couldn't of picked a worse 48hrs, got drowned setting up, everything was caked in mud. Still blanking my Harris off. At least it was dry this morning.
Nice to get on the bank
