Sito Kinetic Polarized Sunglasses
Pickup currently unavailable at BSS
Bold Geometry, Sustainable Build
The Sito Kinetic is a polarized square sunglass with an angular, geometric frame silhouette that makes a strong visual statement. The chunky acetate construction is plant-based, making it a more sustainable choice without sacrificing structure or durability. Whether you are on the water, on the street, or anywhere the light demands serious eye protection, the Kinetic delivers the optical clarity and style confidence to match.
Plant-Based Acetate Frames
Sito constructs the Kinetic from plant-based acetate, a bio-derived alternative to petroleum-based plastics. Acetate frames are known for their rich depth of finish, lightweight comfort, and resilience over time. The material holds its shape well across temperature changes, which matters when you are out in South Florida heat or spending a day on the water. The thick, sculpted profile gives the Kinetic its signature presence without adding unnecessary weight to the bridge of your nose.
CR 39 Polarized Lenses
The lenses are CR 39, the optical-quality thermoset polymer widely used in quality sunglass and prescription eyewear. CR 39 offers excellent optical clarity, superior scratch resistance compared to standard plastics, and a lighter weight than glass. The polarized coating cuts horizontal glare at the source, eliminating the blinding reflection off water, sand, pavement, and car hoods. The result is true color contrast and sharper definition in high-glare conditions, not just darkened vision.
Fit and Frame Dimensions
The Kinetic is sized and proportioned for a confident, face-framing fit. The lens width (A) measures 54 mm, the lens height (B) is 36.5 mm, the bridge measures 20 mm, temples are 145 mm, and the total frame width is 145.4 mm. These dimensions place the Kinetic in a medium-to-wide fit range with a bold, square aesthetic that suits a variety of face shapes.

Sustainable Packaging
