The difference between nylon and Kevlar is weight which generally Kevlar is around two pounds lighter and due to the strength of the Kevlar the blanket is a little thinner and easier to work with around the transmission but the nylon works well in a sportsman type application.

Blanket weights four pounds as seen in the pictures and Kevlar is typically two pounds lighter.
