I have a nearly brand new set of Meander Criou PVC coveralls size 3B. I've used these on exactly 3 trips, and before using them I added seam sealer to the knees. They have no damage. They are too big for me and I need to get a new smaller pair. These sell for $170 at IMO [1]. They can be yours for $100+shipping. Please have a look at the pictures and PM if you're interested.
