Bell's forced air helmets feature the new Quick Lock forced air nozzle that locks the forced air connector in place yet allows for easy release when it is time to exit the vehicle. The smaller nozzle design helps accelerate airflow into the helmet. The Quick Lock nozzle can be used with traditional 1.5 inch diameter forced air hoses by using the air adapter kits that connect the hose with the Bell Quick Lock nozzle.Straight Nozzle Adapter.
