The Tifosi Crit Enliven Bike Sunglasses are best-selling sunglasses that will help you challenge your best times, on the road, trail or running track! The Crit’s vented lenses decrease fogging and the fully adjustable, slip resistant hydrophilic rubber arms and nose pieces ensure a custom fit. Virtually indestructible Grilamid TR-90 nylon frames keep the Tifosi Crit Enliven Bike Sunglasses lightweight, and the wrap lenses protect your eyes from harmful UVA/UVB rays. The stylish crystal black Crit 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 sunglasses include a zipped hardshell case and a microfibre cleaning pouch.
