Ronny makes a breathable wader that comes in bootfoot or stockingfoot and is touted as indestructable. It has a titanium fiber woven into the breathable fabric. The manufacturer at the Sportsmen's Show was dragging pieces of rusty barbed wire across the fabric to demonstrate it's durability. They shipped a pair to a friend of mine who gets all the freebies and we put them through the paces last winter on the SW coastal streams. It was fun making him bushwack through clearcuts full of blackberries, over barbed wire fences, even a tangle with some old logging cable with masses of broken wire sticking out of the mainline. No leaks first winter of use. They have a thin layer of neoprene in the butt and knees for padding. Downside...about $375.
