Bell Sidetrack II MIPS Youth Youth Bike Helmet

Bell Sidetrack II MIPS Youth Youth Bike Helmet

FUSION IN-MOLDING POLYCARBONATE SHELL - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet. INTEGRATED MIPS (MULTI-DIRECTIONAL IMPACT PROTECTION SYSTEM) - MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts. ERGO-FIT - What was once ErgoDial now has an improved dial feel and function (no longer requires a push to turn) and is more sleek and less bulky. NO-TWIST TRI-GLIDES AND SWEAT GUIDE - Quick-adjust fasteners that help keep straps flat and properly positioned. Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear. SPECIFICATIONS - Universal Youth (47-54 cm) and Universal Child (50-57 cm) Sizes. Important: always take a head measurement. Head sizes and shapes can vary, even within an age range. Using a helmet that does not fit can be dangerous; 14 Vents.
