Let's start with the helmet shell made using the In-Mold process. It makes the Scamp not only lightweight, safe, and well-ventilated, but also very durable. The Roc Loc Jr. adjustment system is another great feature, allowing for quick and easy adjustment to the right head size. The wide size range ensures long-term use. All these features become irrelevant if the child does not want to wear the helmet. No MIPS.
