Designed for kids, by kids (at heart), the Thousand Jr. Collection has everything your child needs to stay safe and express their unique style on the road. Made to empower kids to dream big, express themselves, and create their own world, the collection is customizable, safety-certified, and designed to grow with your child for years of fun and safe riding ahead. FEATURES: Every helmet comes with a pack of removable, reflective stickers for customization and creative expression. Our helmets are CPSC, ASTM, and CE certified for biking, roller skating, and skateboarding – so they'll keep safe no matter what wheels they ride. Just one helmet will last your child for years thanks to the adjustable dial fit system, which allows their gear to grow with them (from 49-53cm head circumference). Keep them snug and secure with our eco-friendly vegan microfiber straps, complete with a chin pad for added comfort. No more crying over pinched skin with our easy-to-use and safety-tested magnetic fastener. 6 strategically placed vents actively capture airflow and pass it through the helmet's interior channels. Because kids get sweaty.
