Whether your idea of fun involves a fly rod or a SUP board, these Smith sunglasses give you the unmatched clarity and secure fit for life on the water. Beneath the subtle cat-eye frames lie performance-driven details, such as a thick temple that blocks sunlight and polarized lenses that cut glare. To secure the fit, we added Megol pads at the nose and temples as well as spring hinges that self-adjust to your face. But the real kicker is our PivLockT leash retainer. May you never lose another pair of shades to the waves.
