Make a statement as you toe the line with clean style and total clarity with the Bliz Matrix Sunglasses. Designed for performance, these glasses offer protection from the sun's harsh rays, while packing in Unbreakable Polycarbonate technology for a lens that claims crash-proof safety when things get a little too wild. The frames are crafted from Grillamid TR90, which offers flexibility at a minimal weight to keep you comfortable, and relieve pressure from your temples. To allow air to flow through, the frames are built with vents along the top that let the breeze in to keep you vision fog-free on climbs that get the sweat pouring.
