SCICON AEROTECH PHOTOCHROMIC SUNGLASSES

£225, sciconsports.com

Provided in a sturdy, carbon-fibre-effect case with a bottle of lens cleaner and a nifty little screwdriver to help make adjustments, the Italian-designed Scicon Aerotechs have flexibility in mind. The lenses are interchangeable, as is the ‘fender system’ which sees small bumpers fixed to the bottom of the lens.
