Built with Mips® protection and a lightweight, ventilated design, the kids' Smith Wilder Jr. Mips bike helmet keeps the air flowing as they pedal and pump their way up and down the trails.
Rotational motion can cause brain injuries; with Mips, a low-friction layer slides 10 to 15 mm in all directions, reducing rotational motion to the brain during impact
In-mold construction keeps the helmet lightweight
21 fixed vents and integrated AirEvac ventilation keep the air flowing and your kid's head cool
Built-in slots let them secure sunglasses between laps
VaporFit adjustable fit system easily adjusts with the turn of the dial
Performance comfort lining and ultralight single-layer webbing
