Knockaround Pacific Palisades Polarized Sunglasses. Our laid-back, summer-worthy Pacific Palisades sunglasses get a touch of sophistication in matte tortoise shell frames with polarized amber lenses. There's a hint of old Hollywood thanks to the retro brow bar and rounded rectangular lens shape of our Pacific Palisades, making them the perfect companion on a top-down cruise or stroll along the boardwalk. You can always count on both style and safety from Knockaround in the form of UV400 protection and impact-resistant lenses.
