Sito Good Life Sunglasses

Big Round Energy, Built Responsibly
The Sito Good Life delivers an oversized round silhouette with the kind of presence that stops people mid-sentence. Chunky plant-based acetate frames carry real visual weight without the environmental cost of petroleum-derived plastics, and the gradient lenses tint smoothly from deep at the crown to near-clear at the chin so your view stays true. Every pair ships in sustainable packaging.
CR 39 Lenses with Full UV Protection
Sito specifies CR 39 optical resin for the Good Life lenses. CR 39 is the benchmark lens material in quality eyewear: lighter than glass, more scratch-resistant than most standard plastics, and optically sharp across the full field. The lenses block 100% of UVA and UVB radiation, so you get real sun protection alongside the style.
Plant-Based Acetate Frames
Conventional acetate is petroleum-derived. Sito sources a plant-based acetate for the Good Life, which uses cellulose from natural feedstocks instead. The result is the same rich, polishable look and the same comfortable weight of traditional acetate, with a lower environmental footprint. The frame width measures 150 mm across, giving the frame its signature oversized proportion without feeling fragile.
Fit at a Glance
The Good Life is cut for a broad, relaxed fit. The wide bridge (23 mm) seats the frame away from the face so the lenses clear lashes and the nose sits comfortably without pinching. Long temples (145 mm) reach back to hook securely over the ears. The large lens area, 54 mm wide and 48 mm tall, covers generously while keeping the profile distinctly round rather than oval.

Frequently Asked Questions
- Are the Sito Good Life sunglasses polarized?
- The Rithum product data specifies CR 39 lenses with 100% UV protection. Polarization is not listed as a feature of the Good Life. If polarization is a must-have, check the variant details or contact Island Water Sports before purchasing.
- What does CR 39 mean for sunglasses lenses?
- CR 39 is a lightweight optical resin developed for precision eyewear. It is sharper across the field than standard polycarbonate, more impact-resistant than glass, and about half the weight of glass, making it a preferred material in quality fashion and sport sunglasses.
- What are plant-based acetate frames?
- Plant-based acetate uses cellulose sourced from natural feedstocks rather than petroleum. It has the same look, feel, and workability as conventional acetate but with a lower environmental impact. Sito uses it across the Good Life to align with their sustainable packaging commitment.
- How do I clean and care for my Sito Good Life sunglasses?
- Rinse with fresh water to remove salt, sand, or sunscreen residue. Wipe lenses with a microfiber cloth. Avoid paper towels or clothing fabrics, which can scratch CR 39 resin. Store in a hard case when not in use and keep away from prolonged heat (dashboards, seat pockets in direct sun).
- Where can I buy the Sito Good Life sunglasses?
- The Good Life is available in store and online at Island Water Sports. Shop directly on this page to add to cart and have your order shipped or pick up in South Florida.
- Are Sito Good Life sunglasses good for the beach?
- Yes. The 100% UV protection blocks all UVA and UVB rays, which is the baseline requirement for any beach or on-water use. The oversized round lens area covers generously to minimize peripheral light. Rinse frames and lenses with fresh water after salt exposure to preserve the finish.
