Blanket is SFI 4.1 certified and has durable sewn on nylon straps to allow the transmission to be installed or removed from the race car. Blanket is made from Kevlar or nylon. Difference between nylon and Kevlar is weight which generally Kevlar is four pounds lighter and due to the strength of the Kevlar the blanket is a little thinner and easier to work with around the transmission.
