The MET Crackerjack is simply the most popular of all our youth helmets, developed with the very same rigorous testing and specifications as our adult line of products. Young riders deserve the best, not only in safety, but exceptional design and a style they’ll love to be seen in. To boost visibility of the MET Crackerjack, we included a built in rear LED light, which can be used at night to ensure they are always safe and seen. One of the MET Crackerjack’s greatest features is the adjustable sizing. The helmet can be increased in size from 52 to 57cm, ensuring the helmet will grow along with the child.
