Tac Glasses 2.0 are the Self-Cleaning Polarized Sunglasses that you need. All you have to do is slide the lens up and down to clear them of any rain, dirt or smudge. Perfect for when you're driving or even when you're hiking, on the water or on the slope. You can always wash them clean with running tap water to restore their performance. Tac Glasses have built-in microfiber cleaning pads hidden at the top of the frame. As you push the lens up and down, they clean the front and back of the lens at the same time. Not to mention, the polarized lens blocks harmful UV rays and glare, helping to improve visibility against reflective surfaces. Don't worry about whether the Tac Glasses will fit -- Tac Glasses are one-size fits all. Color: Black.
