In more ways than one, the super-sporty AeroLight Reactiv Sunglasses were designed for you to forget you're wearing them. Weighing less than an ounce, they'll feel as close to weightless as you can get, allowing for greater comfort and a distraction-free feel. They've also got photochromic Reactiv lenses that react to changes in light conditions, so you won't even need to take them off when a dark cloud rolls through or when the sun begins to set. You won't be constantly adjusting your glasses thanks to the fully-adjustable nose pads and shock-absorbing temple grips. The super-wide lens design also ensures full coverage, so the next time you'll remember you've got them on is when you're getting funny looks inside at the post-run pizza spot.
