Our legendary collaboration continues with Hendrick Motorsports. And we went all out. Bringing the iconic City Chevrolet livery to our Heat Wave heavy hitters.  Boasting the same great features as the standard Vise®, The XL version is the first pair of (you guessed it) EXTRA-LARGE Heat Wave frames specifically designed for the ones with larger than average heads.  We took the time-tested design of the Vise® and added an extra 10mm in width and jacked up the ride height to 5mm to provide Godzilla-like, larger than life comfort and coverage. Lens Technology: 1.9mm thick Polycarbonate lens that meets or exceeds impact requirements for Z80.3 standards, injection molded to the highest standards and tested to ensure optimal clarity, along with color and light transmission standards. We use only the highest quality polarizing filters on our lenses for optimal glare reduction and supreme clarity *Available in both non-polarized and polarized options* Lenses are U6:L3 UV400 - 100% UVA / UVB blocking Radium Green Lens VLT = 10% / Cat 3Radium Green Polarized Lens VLT = 10% / Cat 3
