The Atomic Four JR is a complete protection package for young guns, with the same understated, urban style as the Atomic Four adult models. Plus, you can now remove the liner and ride with a hat and goggles under the shell if you wish. It's comfortable and cool and features Atomic Aircon, an advanced cooling system that actively draws hot air away from the head. And of course, like all Atomic helmets, it offers supreme protection—with an in-mold shell and an Atomic Holo Core that absorbs shock and generates up to 30% more impact protection than industry standards require.
