The Supernova Sunglasses from Koo are absurdly lightweight, weighing in at a feathery 21 grams. They are designed for those who value high performance for road cycling or running. This low weight is achieved with a minimalist frameless design that also maximises the field of view. The hydrophobic, anti-fog lens is interchangeable for different light conditions or if the original becomes damaged. The Supernova's, as with all other Koo sunglasses, are 100% made in Italy, so quality is guaranteed.
