Helmet sizing
Getting the size right
A helmet only protects properly when it sits level and snug. One measurement is all you need.
Measure around the head about 2 cm above the eyebrows, keeping the tape level.
Use a soft tape measure. A piece of string held against a ruler works just as well.
Match the measurement to a size below. Between two sizes, take the larger and use the fit pads.
Check the fit: level on the head, low on the forehead, and no rocking side to side.

About the YOMO KIDS’ Helmet
Added to cart
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.
