So, I have a Buffalo Artic Parka, and being a complete pillock I have managed to tear an L shaped rip, each arm about 1" long. It is made of Pertex, and so is very fine material. Any brilliant ideas on how to patch it? I tried an iron on web material, kind of from the inside if you can imagine it. Unfortunately, it did not hold that well and has come away quite quickly.
Any ideas?
