This is what matters most when choosing a kids’ helmet. You can look for certain safety features, including our Mips® safety system and other special functions, but the first step is to make sure the helmet is certified to helmet standards in your country. There are many different standards worldwide, but some of the most common ones include Europe’s General Product Safety Regulations (GPSR) and the Consumer Product Safety Commission (CPSC) in the U.S. Any helmet you are considering purchasing for a child should be certified by the latest safety standards. WARNING. NO HELMET OR IMPACT PROTECTION SYSTEM CAN PROTECT A USER FROM ALL INJURIES. ALTHOUGH THE MIPS® SYSTEM HAS BEEN DESIGNED TO REDUCE ROTATIONAL ENERGIES TO THE HEAD, WHICH MAY LEAD TO BRAIN INJURIES, THERE ARE LIMITS TO THE PROTECTIVE CAPABILITIES OF ALL HELMETS, INCLUDING HELMETS WITH THE MIPS® SYSTEM. USERS ARE WARNED NOT TO REMOVE, REPOSITION OR OTHERWISE TAMPER WITH THE MIPS® SYSTEM IN A HELMET OR USE A HELMET WITH THE MIPS® SYSTEM IF THE MIPS® SYSTEM IS DAMAGED OR DISPLACED. Driveway laps? Riding to school? Learning to jump at the local bike park? Most bike helmets for kids are versatile enough for different riding styles, but if you have a young mountain biker or future road racer, you may want to consider one that targets those types of activities. For more advanced young riders, consider the helmet construction: Higher-end helmets are usually made with in-mold construction, with a polycarbonate outer shell ponded to the EPS foam layer so that the two form a single piece. This type of construction usually results in lighter, more ventilated helmet options.
