I bought a new helmet. Giro Syntax MIPS

My old Bell Furio needed new pads. I had bought them once before. Cleaned everything and was good for another few years. This time I decided to get something new. This Giro is labelled MIPS which seems like the foam is thicker. The strap system and adjustment are pretty much the same as the old Bell. So what did MIPS actually get me? Other than a fun trip to the store with my Grandboy, he got a new soccerball.
