I guess what they call the 3rd layer is a fuzzy texture on the inside of the shell. This makes the jacket very comfortable and it doesn't stick to your skin like other jackets do. I wore this recently on a very warm humid rainy day with just a t-shirt on underneath. I was literally wore comfortable with the jacket on than off. The material just kind of sucks the moisture right off your skin. The jacket seems very durable too. I have the black which is more of a dark charcoal grey, but very nice.
The black jacket is more of a charcoal grey, but is a really cool color. This jacket is awesome for the price.
