Due to the hot weather here in Okinawa I am thinking of buying an Air Tech Mesh jacket. I here they are quite comfortable for riding in hot/humid weather. Can't afford leathers and these jackets are not too pricy. How much protection can a jacket like this provide? I know it has pockets to insert armor in the back, elbows, etc. Should I buy one or go with something else? If something else please give me a suggestion.
