Helmet GPX 5.5 Jr Solid White

$359.99

Lightweight Composite Off-Road Helmet for Juniors

Specifically designed to protect younger riders, the GPX 5.5 Composite Junior helmet boasts the same technology that makes the adult helmets so effective. Lined with turbines which is soft and flexible to the touch but instantly hardens upon impact, the helmet works even better the faster or harder you fall as these turbines act as an energy absorber during a crash.

The helmet’s 360 ̊ Turbine Technology reduces up to 30% of head impact at concussion level and up to 40% of rotational acceleration to the brain. Other safety features include the 3D in-molded V-foam and a 10% smaller shell size, transferring up to 20% less rotational forces to the neck, head and brain, as well as the breakaway visor that reduces rotational reduction in a crash. For additional convenience, the helmet is neck brace compatible, hydration ready, and has removable cheek pads for emergency situations. As a bonus, it is nice and comfortable with a ton of ventilation.
