The H70's Advanced Fiberglass Composite construction comes configured in two shell sizes for maximum comfort and a perfect fit. The removable head liner and cheek pads are washable to keep your helmet's interior fresh and ready to go for race day (ear cups may be installed to reduce engine and road noise, sold separately). The 2 front intake vents and 8 top vents create advanced air circulation to make sure your head will stay comfortable the whole drive. A rubber seal around the H70's eye port helps keep dirt and water out so you can stay focused on the course ahead. Snell SA2020 and FiA 8859-2015 approved.
