Fijne lichtgewicht helm. Past goed op het hoofd en ziet er goed uit.

What a great helmet! I have size M/L and the fit is absolutely good While riding, you almost don't notice you are wearing it. I wear glasses and with they fit behind the visor without touching the glass which is excellent. You also do not suffer from wind at all, which is very nice if you have sensitive eyes like me. Recommended for 100%!

Waarom zou je nog twee helmen kopen? Dit is een hele lichte helm, ideaal voor mtb en voor op de weg. Om met de mtb te beginnen: Doordat het vizier aan de helm zit, heb je nooit last van een bril die scheef op je neus gaat zitten. Ook beslaat die niet omdat de afstand tot je ogen altijd groot genoeg is. Door de ventilatiegaten is er genoeg verkoeling. Het grote vizier biedt meer bescherming tegen takken en zand in de ogen dan een kleinere bril. Dan de weg: dankzij de aerodynamische vorm en het compacte formaat is een aparte helm niet meer nodig. En met 255 gram ook zeer geschikt voor het hooggebergte. Ik heb voor wit gekozen. Extra koel. Al met al een tophelm!

Leichter, gut sitzender und windschnittiger Helm. Super Qualität. Zusammen mit dem Sky-Visier optimal für Rennen.
