What Our Gearhead® Experts Are Saying:"These are the kind of sunglasses I grab for everything—trail strolls, brewery runs, and weekend drives. The Sielo fits super comfortably, stays put thanks to the grippy nosepads, and the Prizm lenses make every scene feel just a little more vibrant."With the Oakley Sielo Prizm Sunglasses, clean design meets performance detailing for a frame built to keep up from town to trail. Drawing inspiration from wide-open skies and a spirit of movement, the Sielo features a sophisticated blend of lightweight BiO-Matter™ and C-5™ metal for day-long comfort and style. Unobtainium® nosepads and soft-touch earsocks provide a secure, no-slip fit, while the signature Prizm™ lens technology enhances color and contrast for richer detail across bright, sunny conditions. Whether we’re stepping into a back alley art fair or chasing golden hour at a trailhead overlook, the Sielo’s versatile silhouette and performance-driven features make it a natural companion for all-day wear.
