I have an old pair of OR goretex mittens. The outershell is in fantastic condition, but the goretex laminate has worn off of the interior on the palms of both gloves. Worse on the left - I am left handed and tend to carry treking pole in the that hand most often. I really do not want to replace these, but would like them to be water proof again. I do not care if they are breathable in the repaired area, but am more concerned of skin contact with some toxic or smelly chemical - like, if I patched this area with silicone and them had my hand in them for a long day it might not be good for me. And I use them more often without a liner glove than with. But if I had to I could get a thin liner glove to wear. I am open to repair suggestions and would really like to be able to continue using these mittens. What the worn/damaged area looks like is --- donut icing peeling off or like when the pu coating comes off the nylon.. Not sure if that is a good description.
