Product InfoThe Giro Spur Mips Jr. helmet is a great bang for your buck in terms of quality comfort and safety for your little shredder. Equipped with Mips (Multi-directional Impact Protection System) to offer the best in rotational impacts. Super cool venting to keep them cool and comfortable all day. Giro's In form fit system allows for 6 cm of adjustability for the perfect fit. Its a great little package to keep your little ones safe and comfortable as they explore the mountain. The main components of a Mips-equipped helmet are the interior foam liner, the low friction liner, and an elastomeric attachment system. In an angled impact, the elastomeric attachment system stretches to allow the foam liner to rotate independently around your head. In-Mold Construction In-Mold Construction fuses a tough polycarbonate outer shell with the helmets impact-absorbing foam liner. The fusion process allows for better ventilation systems, making In-Mold helmets lighter and cooler than traditional helmets. In Form 2 Fit System The In Form 2 System is lighter and lower profile than the original, making it even easier to dial in a custom fit in secondseven with gloves on. The updated On-The-Fly Vertical Tuning feature accommodates different goggles and head shapes for a custom fit free of gaper gap.
