We've managed to source some pretty special cycling specific sunglasses from boutique Italian brand Power Race.
Featuring a frame made from virtually unbreakable Grilamid TR90 nylon, known for its high bend strength, low density and high resistance to chemical and UV damage. The result is a frame which is as light as it is robust, with a nosepad made from hypoallergenic compund that's designed to stay comfortable while still releasing sweat.
Ultra-thin (1.1mm) lenses continue the lightweight theme, not at the expense of durability however, with each lense being both foldable and shatterproof. No need to worry about fumbling with them on the bike then.
Complete with 3 sets of interchangeable lenses: Red or Blue (dependent on model) for low-light overcast days. All with full UV protection.
All lens have an hydrophobic and oleophobic coating to prevent water and grease smears or streaks, plus outstanding anti-fog performance.
