This Kids? Glide Jr. MIPS Helmet is lightweight and durable, with its in-mold construction that fuses the outer shell and inner foam to create a one-piece design. Fitted with a MIPS Brain Protection System, this helmet reduces rotational forces acting upon the head caused by angled impacts, keeping your little one safe. An adjustable dial means the fit is exact and secure and the soft, fuzzy lining is warm and comfort for all day wearing. Fixed vents allow constant airflow for ventilation and the helmet also has an AirEvac ventilation system that integrates with Smith?s goggles for effectively mitigating fog build up in your lenses.
