Kid size helmets wanted

One word

E-bay

Take a look at the Kimpex ones. Great price and cool graphics for kids. Make sure you pick the ones with the double shields.

brands to consider...

Greetings,

If you're looking for full-face check out Gmax GM39YS, HJC CS-Y or the Z1R Strike. All come with breath guards and dual pane shields.

If your looking for more of a motocross-style helmet, consider the HJC CL-X5n or Scorpion VX-9. Also consider brands such as Z1R and Gmax - both of which make youth helmets. You'll need to purchase a breathguard for these, a good pair of snowmobile goggles and I would recommend a headsock. Cheers!
