Five out of five, that’s the Atomic Four Helmet. This is a low-profile and very cool looking helmet that, like all Atomic helmets, exceeds safety certification requirements by at least 30%. That’s the kind of pulse-slowing confidence parents can get behind! Not saying you should encourage an abandonment of speed checks in the family altogether, but it’s nice to know the most important people in your life are well-protected. The Four Helmet has all the best features of adult helmets, sized down for your little ones’ heads.
