Giro likes to advertise that the new Synthe is two percent cooler than their ventilated Aeon helmet and certainly more than the Air Attack. In fact, Giro used a special proprietary system called a Therminator to figure that out. But we'd also like to point out an overlooked and identically-named metric that Giro hasn't mentioned: coolness. The Synthe, in our opinion, is 100 percent cooler-looking than its siblings. As you can see in the top photo, it doesn't look like a damn toadstool on Taylor Phinney's noggin. To get people to be safe and wear helmets, it doesn't hurt to look good. And yes, it comes in black.
