Pro-Tec Jr Classic Certified Helmet Pro-tec have taken their proven, tried and true style Classic helmet and miniaturized it for the youngest of rippers. The newly added Twist Fit system provides dual-direction ratcheting adjustment, for a more custom fit without having to mess with changing liners. They've also added a magnetic Fid-Lock buckle which is easier to use for little fingers and eliminates those pesky neck pinches.
