Sines - Unisex Bio Acetate Sunglasses

The Sines Unisex Bio Acetate Sunglasses are built from Italian Mazzuchelli bio acetate, a plant-derived material composed of wood pulp and cotton fibers bound with natural plasticizers including citric acid esters. The result is a frame with genuine material transparency, a classic squared silhouette, and a fit that works across face shapes. Available in Tortoise Shell, Black, and Champagne, with frame measurements of 50-21-140.

• Bio acetate frames sourced from wood pulp and cotton fibers with citric acid ester plasticizers, offering a plant-based alternative to conventional petroleum acetate.
• Nine-layer lenses combine two scratch-resistant layers, two shock-resistant layers, four UV400 layers blocking both UVA and UVB rays, and one polarized layer for glare reduction in bright conditions.
• CE (EU) and FDA (USA) approved lenses with a changeable lens design, so the frame stays in use longer rather than being replaced entirely.
• Backed by a 2-year warranty, supporting the kind of longevity that reduces the cycle of disposable eyewear.

Style that holds up to real wear and leaves a lighter footprint. The Sines sunglasses are a considered choice for anyone who wants optical clarity, ingredient transparency, and a frame worth keeping.
