I've got a pair of the breathable waders and really like them. They have lasted longer than any pair of neoperene waders I've bought, are comfortable, and I can wear plenty of warm stuff under them for the winter.

One possible problem is that they apparently are not meant to be submerged very deep. Water preasure will force water through. My brother bought a pair and he had problems with leaks when he used his float tube. As far as I know he has not had any problems with his kickboat as he sits higher out of the water.

So if you use a kickboat they should work for you. If you use a tube, ping my brother (Swampy) and ask about his experiences.
