I have some PVC rainwear from PVC U Like , which I use to walk in the rain.
They are of a good qulity , but the hoods are too big.

If I want to fasten it, it is pulled around my face ,so I cannot see anything.
The hood of a poncho from PVC U Like fitts good, because it is smaller.
How can I make it smaller ?
I tried something with tape , but that does not stick, the plastic is too smooth and gluing destroys the pvc.
Has somebody an idea?
Greetings , Peter
