Alright, so might be in the market for a new helmet and with the suggestion to replace them every 5 years, and now having 3 little kids, the thought of spending $500 on another Shoei ain't going to cut it with the wife. So, saw the Fly Trekker (in hi viz yellow thank you) and the reviews are pretty good. Does anyone have one of these? At around $150, you can't beat the price, but how good is the helmet? Does it flow a lot of air? I'm headed to California and with 105 degree summers, I'm looking for high air flow. Thanks.
