Tifosi Tyrant 2.0 Clarion Interchangeable Sunglasses. Unlike Stalin and Mussolini, this is one pair of tyrants that you can depend on to protect you. The Tifosi Tyrant 2.0 Clarion Multi lens cycling glasses are made of a tough TR90 lightweight nylon with borderline shatterproof polycarbonate lenses, so they're always there to stand between your eyes and glare, debris, or grime. Plus, with 3 sets of lenses, you can outfit these frames for any riding situation, and with vents on the side, you can say goodbye to fogging. Tifosi's nose and temple pieces become tacky when wet so they cling to you just how you want them to...even if you're pedaling hard.
