Here in FL, I've been using a Joe Rocket textile jacket for the summers.
It may not provide the best protection over leather in case of a fall, but it at least provides great ventilation once moving, which is at a premium here.
There's some back, shoulder, and elbow armor protection.
I had some of their textile pants, but I never could get them in a proper size to fit.
Plus the durability wasn't near what the jacket was.
Shop around and try various brands on for quality, fitment, protection, etc.
