Review on I90 Flip-up Helmet by HJC Helmets by Bohyun Rossetti

It makes a good winter helmet but will boil your head in the summer. It has a small intake port in the front and even smaller "exhaust" ports in the back. That's all. When I took the pad out there were only two small holes in the foam for the intake and two small holes for "exhaust". After I put the liner back in place, I noticed that the liner covered about half of the holes. Rode it in 90 degrees the other day and it was almost dangerous how hot my head got. Too late to return now as everything seemed fine with milder weather. It's a shame too because I love everything else about it.
