The Atomic Four JR Helmet is the full protection package for young guns, all with the same urban-inspired low-profile style as the adult Atomic Four models. As part of this, you can now remove the liner and ride with beanie and goggles under the shell if you want. Its comfy and cool and comes with Atomic Aircon, an advanced cooling system that actively sucks hot air away from the head. And of course, like all Atomic helmets, it delivers protection with an in-mold shell and Atomic Holo Core that absorbs shock and generates up to 30% higher impact protection than industry standards require.
