I really like patagonia waders. They are know for their ironclad warranty. i put a hole in one. So they refunded my money after 2 years of use. Then bought another and they patched that up for free. Their customer service is really awesome. They are currently selling a pair for $180 from 300. The waders them selves are really tough. The holes that i got are from knife like rocks.
