The Atomic Four JR is the complete protection system for young riders, with the same cool, urban style as the Atomic Four adult models. With this helmet, you can now remove the liner and wear it with a hat and goggles if you wish. It's comfortable, cool, and comes with Atomic Aircon, an advanced ventilation system that removes hot air from the head. And of course, like all Atomic helmets, it offers supreme protection, with an in-mold shell and the Atomic Holo Core, which absorbs shocks and generates up to 30% more impact protection than required by standards.
