This was a great helmet! I bought this helmet for the 2014 racing season. I loved for the early year cold weather crits. It even seemed to be pretty comfortable in hotter conditions like at collegiate nationals this year. I'm positive that it saved me some watts. However, I believe the most overlooked feature of these helmets are their ability to protect. I crashed into a car recently, and this helmet took the majority of the damage and completely saved me. Thank you giro for great engineering, and I will definitely buy another!
