The SQUAD JUNIOR is a hard-wearing helmet designed for intrepid youth who do their best to challenge the force of gravity. Its decidedly rigid construction, with an EPS core to absorb shocks and a lightweight but durable ABS shell, is synonymous with greater protection, functionality and style. The MarkAir CHANNEL system and the RTS knob for adjusting the head circumference ensure easy operation, perfect fit and exceptional temperature control. If you prefer to wear a hat under your helmet, the high-performance X-Dry liner can be removed in an instant.
