The Tifosi Slice Enliven Bike Sunglasses provide fantastic frameless optics. Their organic, curved lens and aggressive arms provide a dynamic look. Ideal for triathletes and runners, and weighing only 29g, this is the one of the lightest shield lens interchangeable models in the Tifosi range. The stylish crystal black Slice comes equipped with Tifosi’s Enliven Bike Contrast Enhancing lens, to fine tune the wavelengths of light that matter most – making greens, reds and blues all pop with definition. Regular colour-tinted lenses enhance some colours but distort others, but Tifosi’s Enliven Colour Capture Technology enhances all of the key colours without distortion. These glasses include a zipped hardshell case and a microfibre cleaning pouch.
