When it comes to contact sport, body armor is a hot topic. This makes sense: armor protects you. But there is a problem as well: in the world of physical preparation armor is shorthand for size. In the real world that is hardly the case. The best combat armor is not the biggest. There is a reason modern soldiers don't go onto the battlefield dressed as a medieval knight. To be effective armor has to be strong. It needs to allow movement. It needs to protect the most vulnerable parts. It needs to connect to the body. Size is the least concern in most cases.
