I just made it through my 5th season on mine,my sister bought me a pair of Cabelas wet lands 3.5mm neoprene back in 2002.
I mainly use them for the canal I've sat on rocks,nelt on them and even takin a couple of good diggers I've have a couple of pin holes but nothing major.
They still holding up so Im in no rush to buy some fancy Gor-tex one's
