RE:OS Systems Waders
Doug you sound like me before I bought these things. After my second pair of Hodgman Neoprenes I came across these things. I could care less about whether they're breathable or not. Once you're in the water you stay cool, out of the water they're light as a feather so you can carry easily on a long hike.
Believe him when he says 9 years. I fished these things hard for their first two years and they held up great. I was worried about the latex stocking feet holding up but haven't had any problems yet.
In fact, like Juro said, they're not only tough but give you the option of keeping your feet cool in the summer.
