Tim, I have something similar to that. I wear it for some long distance, but don't care for it really. If it starts to rain it is really really cold. For trail riding I have a Shift plastic moto roost guard. I like the protection. The Jacket feels naked on the trail, like if I fell off I would break a rib. I would get a coat that is more substantial for commuting, and moto-gear for off-road.
Most importantly, buy good boots.
