Greetings, I am in the market for my first trials helmet. I have searched most of the trials forums, and did not find much on the Airoh, except what was on Web Bike World. They gave it a good evaluation at a premium cost, but I am looking for some real world history. From what I have learned, protection and ventilation are important, but can this be achieved with a lesser priced helmet, such as the Shiro? I am still waiting for a return call from Lewissport on this question. Thanks for the input.
