Atomic Four JR CTD

Designed for adventurous youngsters, the Atomic Four JR CTD combines ultimate protection with our signature urban-inspired Four style.

Atomic Aircon Venting keeps the helmet comfy all day thanks to an advanced cooling system that actively sucks out hot air. And you can remove the liner of this low-profile model to wear beanies and goggles under it without sacrificing protection.

The in-mould shell and Atomic Holo Core means that, like all our helmets, it has incredible shock-absorbing properties. In fact, it gives the wearer 30% higher impact protection than industry standards demand.

Not to mention our new smart-helmet Shocksense technology, which monitors helmet impact-damage and has an in-built SOS function. It’s the complete package, where style meets supreme protection.
