Proof Men's Butte Eco Polarized Sunglasses

As part of Proof's Eco collection, the Polarized Butte Sunglasses are made from a cotton-based acetate which is fully bio-degradable and will naturally go back into the earth when they are no longer wearable. These shades are designed to tackle days full of hiking, biking, and fishing with polarized protection that keeps your vision clear with enhanced colors and reduced glare. The lenses are also water- and sweat-resistant to deflect moisture when you're getting after it, while spring-loaded stainless steel hinges provide a shape that fits most faces.

Plus, the included microfiber bag wipes down your mud-spattered shades at the end of the day before you store them in the also-included wooden box.
