ProTec took their proven, tried and true style, The Classic, and miniaturized it for the youngest of rippers.
Their newly added Twist Fit system provides dual-direction ratcheting adjustment, for a more custom fit without having to mess with changing liners. They also added a magnetic Fid-Lock buckle which is easier to use for little fingers and eliminates those pesky neck pinches.
Available in 2 sizes from 47cm-54cm with 2 sets of pads for a more custom fit. Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older
