It always fits perfectly. Why? Because the helmet and goggles come as a single unit that offers easy size adjustment and a practical ski goggle holder. As the fit has been carefully engineered, there’s nothing in the helmet to pinch or hurt them when they’re out in the snow. And for kids in a hurry, the Monomatic clasp can be opened with one hand, even by the smallest piste pros, ensuring comfort and safety in every situation. Child’s play and child-friendly.
