Got these in Size L to fit in my Dainese Sauris 2 Jacket and they fit (95%). Once they're in and the velcros are strapped in, it looks very good. Hopefully i do not have to find out if these works for real.

There are only two sizes, S and L. What would be the appropriate size for a size M Bogota Pro jacket? Thank you

Answer of cristian

Buy the L, you won´t regret it. I bought size L protections for a TGP plus size L jacket, at one time I sold the protections and a guy who had a size M jacket bought them for me and they did it without problem!
