Nike designs its Essential Chaser sunglasses to keep up with your athletic endeavors. The square frames are made in a lightweight performance plastic commonly used in sports eyewear. The temples curve inward for stability, and boast the iconic Nike swoosh near the brow end. Stop hinges protect the lenses from scratching by preventing the temple from folding down too far. Style and performance are not mutually exclusive—the Nike Essential Chaser is proof positive.
