YOMO Kids' Helmet

Protection they will actually wear.

A helmet only works when it fits properly and feels comfortable enough that a child keeps it on. Every detail here is aimed at both.

Adjustable dial fit
A rear dial tightens the cradle in seconds, so the same helmet keeps fitting as they grow.
Fidlock magnetic fastener
Closes with one hand and cannot pinch skin, which removes the usual argument at the door.
Vegan leather strap
A soft chin pad and smooth strap sit comfortably against the skin on longer rides.
10 vents, cooling channels
Air moves through the shell rather than around it, so heads stay cooler and helmets stay on.
Reflective decals
Catches headlights on darker afternoons and on the ride home from school.
Light but robust
Certified for bikes, skates and skateboards, so one helmet covers most of what they do.
