After years of summer sweating in neoprene waders, a couple of years ago I bought some breathable waders. Two things I wish I'd known. First make sure the sock isn't creased in your boots. One time I didn't realise and the crease wore through and developed a leak. Second, make sure the straps are tightly adjusted so that the waders fit right up to your crotch, despite the unfortunate possibilities. I didn't do this and through creasing and rubbing they have developed a leak, an embarrassing place to have a wet patch!
