The Feher ACH-1 meets or exceeds the US DOT FMVSS 218. The helmet is constructed with a synthetic fiber-reinforced multi-layered fiberglass shell. The ACH-1 weighs in at just 1450 grams (+/- 30 grams), which is competitive with other high-end performance helmets. The ACH-1 also comes standard with an anti-scratch and anti-fog coated face shield to provide clear visibility in varying conditions. Aside from the ACH-1's ability to provide its unique cooling function, it is also a high-performance premium fiberglass motorcycle helmet on its own merits.
