Bend Furious and it will bounce back to 100% of the original shape. Because Furious is engineered from Grilamide TR90. It’s a flexible polymer that's durable in extreme temperature changes too.And in the water Furious works. Because of its fog elimination vents, because of its water escape vents, because of its polarised lenses designed in the harsh sunshine of Australia. But also because of its 4 layers of UV protection and its two added lens hard coatings which add extra protection to the already impact resistant polycarbonate lenses. Water is also repelled with the hydrophobic lens coating.All this on water and dry land, thanks to the detachable headstrap.
