The Wipeout Dry Erase Kids' Bike, Skate, and Scooter Helmet makes any child wearing it the envy of the neighborhood. Unlike traditional helmets, the Wipeout encourages kids to assert their individuality by creating and customizing their own inspired designs on the surface of the dry erase helmet. Each helmet includes five non-toxic dry erase markers in assorted neon colors, as well as a stencil kit with eight awesome shapes so kids can make an art project of their helmet before heading out on any kind of roller sport equipment, including bikes, roller skates, skateboards, and scooters. When it's time to come home, the helmet can be erased and a new design created for the next day of play. The Wipeout Dry Erase Kids' Bike, Skate, and Scooter Helmet features an ABS hard-shell for safety and durability, and is dual certified for bike and skate use, complying with U.S. CPSC and ASTM safety standards for biking, skateboarding, and trick roller skating. Set includes a helmet, five dry erase non-toxic markers, and a stencil kit. Available in two sizes: Ages 5+ fits head circumference 49-52cm; Ages 8+ fits head circumference 52-56cm. For most accurate measurement, use a string to measure the circumference of the head.
