Welcome back to the new NEFF. Take a break from Twitter and Facebook. You don't go to Dicks for your fly fishing gear, you go to your local fly fishing store. Enjoy!
The leak is probably not on the outside layer. The breathables usually have a thin membrane on the inside that looks like a fine mesh. My last pair I wore out this mesh in a one place and they began to leak there. There was no holes or pinholes on the outside of this material. You have to apply the sealer from the inside.
See if you can find sportsmans goop.....It has fixed everything I've put it on. Also you could buy a wader epair kit......I think orvis sells one for breatheables.
