I am in the market to pick up a new roost deflector. I was using the outer plastic chest protector and will most likely continue the trend. I have seen the AXO Full body armor bio foam under jersey protection. It appears to cover full chest and back, and shoulders. I wanted to know if anyone here has ever used it? does if offer protection from crashes, you know, handlebar in the gut protection? The unit sells for $110, so it is about same price as an outer system... Any users out there?
