The Arai Quantum is composed of a Super complex Laminate construction shell, a distinctive new Hyper Ridge reinforcement band and is ECE 22-05/SNELL M2010 approved, making it a very safe and protective helmet. New IQ side exhaust vents, a Free Flow System guided air stream and two TDF3 top inlet ducts easily opened and closed provide great ventilation inside of the helmet. The inner liner material is made of improved two-tone Dry-Cool, and is fully removable, washable and replaceable. This makes for a greatly comfortable fit inside of the helmet.

The helmet is also designed to have a larger opening for increased ease when taking it on and off.
