I have the “Alpinestars T SP X Superair jacket (XXL)”. Is this protection suitable for my jacket? If yes, which size should I buy?

Answer of Yuri Nikolaevich

I have another jacket size XL, for it I took the back protector size L

Answer of Roland

You have to check the inside of your jacket, I have a missile V2, which has a small pocket, which also fits this lengthy one , from the upper side, but not the lower. You should either but this long version with its own straps or tweek it into your jackets small pocket. having ,,the short version is worthless.
