The LO (Long Oval) is the traditional Arai shell shape, designed to fit heads that are narrower from side to side, giving more room at the forehead and alleviating the infamous forehead pinch common with some competitors. Arai's Signet series helmets incorporate the LO shell shape.
The Signet GT also comes with a dual intake/exhaust ventilation system designed to draw hot air out from the helmet's interior, as well as a new face shield release system to make removal easier.
RAI helmets are the first choice for bike racers.
Over $500 new.
