Prada Sport uses a lot of Gore-Tex too but it isn't a technical label. Its just casual sportswear. Miuccia says Prada Sport is the true Prada line. I wouldn't wear it to the gym or play soccer in their trainers but its something you can wear everyday. It might be hard to explain its appeal but I find it futuristic, well-made, comfortable and stylish. Just don't buy the plain t-shirts.
