Designed for adventurous young people, the Four JR CTD from Atomic combines ultimate protection with our iconic urban-inspired Four model. Atomic's Aircon ventilation system is an advanced cooling system that actively exhausts hot air for a comfortable all-day helmet. And you can remove the liner from this low-bulk style to wear a hat and goggles without sacrificing protection. Atomic's molded shell and Holo Core mean that, like all our helmets, it has incredible shock absorption properties. In fact, it provides the user with 30% more impact protection than required by industry standards. Not to mention our new Shocksense smart helmet technology, which monitors helmet impact damage and has a built-in SOS function. It's a complete package where style and supreme protection meet.
