Laster... Vennligst vent...You never know when you will need the strength that Wiley X crafted into these Wiley X Josh sunglasses. Maybe you will never find out. In a world as tuff and unforgiving as the one we live in why take chances? Wiley X realized how much gets throw at your eyes everyday and has built their shades, including this Josh model, strong enough to handle anything this rock can throw at us. After that they took it miles further than that by designing ultra sporty frames like the josh so that we could all rest assured that our eyes were protected and look great doing so.
