The women’s 509 Esses Sunglasses are not your normal designer shades. Like all 509 sunglasses, the Esses is inspired by our unique lifestyle. We go hard, get dirty, and demand sunglasses that can keep up. Featuring Polarized FUSION 5 lenses and shockingly lightweight, comfortable, and tough TR90 Swiss thermoplastic frames, 509 sunglasses are simply built better. All styles backed by a fit guarantee and lifetime warranty.
