The Alpinestars "jacket" has exactly what I need in terms of shoulder protection, but it only comes with built in chest plate and back protector, which I don't want. I need to be able to wear the shoulder protection on long rides in the summer including lots of climbing. Seems like the only options I can find are football wide receiver pads (too big and bulky) or lacrosse shoulder pads (no hard plastic plates over the shoulder). Does anyone know of currently available shoulder gear that is substantial with plastic plates /covers but is not over the top motocross gear? I need to be able to exercise with the things on...
