"This is my second TLD helmet that I’ve owned. I ride single track and race sprint enduros in Northern California. The D4 carbon helmet is light as air with the best safety rating. The vented design stays cool and did I say light as air! Great helmet from a trusted moto apparel/gear company. I highly recommend."
