Tifosi۪s unique Interchangeable Component System (ICS) makes it simple to fit your frame to your activity. Each frame type has a patent-pending notch system that fits into the universal arms. Pivot the arm up and onto the notches until it clicks into place.
The Tifosi Pro kit is available in a wide variety of options, and each frame comes with an extra set of lenses so you۪re always ready for whatever the day brings. All Tifosi Pro kits include a set of universal arms, a custom zippered case to hold all components in place, plus a cleaning bag.
