Like the lava formation in West Maui that they're named for, Maui Jim Dragon's Teeth Glass Polarized Sunglasses are built to withstand the test of time. PolarizedPlus2 technology wipes out glare and stokes the color with a patented multi-layer design. The lenses are made from SuperThin Glass, which provides the absolute crispest optics available. 20% to 32% thinner and lighter than standard glass, they offer the best scratch and solvent resistance. These polarized sunglasses feature Maui Jim's newest frame material, carbon fiber. Carbon fiber is ideal for sunglasses because it's durable, lightweight, and hypoallergenic. The nose pad area is also carbon fiber, while the adjustable temple tips are coated in rubber for a secure fit. Select styles feature mirror coatings for more glare control, a stylish look, amazing color enhancement, and superb clarity. These Maui Jim polarized sunglasses come with a case and microfiber cleaning cloth. Mfrs. 2-year warranty.
