When you're out for long days in the sun, the lightweight Maui Jim Polarized Bamboo Forest Sunglasses are a win win ... win. Their full coverage style with minimal weight and high performance lens technologies provide a trifecta of winning benefits: optimal comfort, excellent color preserving visual clarity, and 100% UV blocking eye protection. The Bamboo Forest manages to provide a ton of coverage with minimal bulk thanks to the Grilamid ultra thin and lightweight frame and MauiPure lenses that are Maui Jim's lightest weight option. The adjustable Rabalon rubberized nose pads allow you to customize a secure fit. The MauiPure lens is scratch and impact resistance and provides optical clarity second only to Maui Jim's glass lenses. A unique polarizing film within the lens nearly eliminates glare while preserving the brilliance of surrounding colors, and if you're around or in water, enables you to see below the water's surface as long as the water is clear enough. An anti reflective treatment eliminates glare from behind the lens, while a waterproof and oil resistant coating on both sides of the lens allows for easy smudge and water droplet removal. Maui Jim throws in a case and cleaning cloth with the sunglasses so you can be sure to wipe your lenses nice and clean and keep the sunglasses protected.
