Actually, I have many of these Prada nylon. I LOVE THEM ! hahah maybe its because i live in London where it rains almost everyday? but no seriously the black one i had for over 3 years i have worn it excessively its so durable.. the other one the purple one i got because i had a matching prada skirt that goes with it. But honestly they might be Nylon but they pass the durability test! and go with everything!
