Sito Outer Limits Polarized Sunglasses
Bold Shape. Polarized Protection. Sustainable Build.
The Sito Outer Limits brings a sharp, oversized square-rectangle silhouette to a frame engineered for serious sun time. Thick handmade acetate construction, CR39 polarized lenses, and eco-conscious packaging make this a do-it-all piece for outdoors and everyday wear.
Plant-Based Acetate Frames
Every Outer Limits frame is handmade from plant-based acetate, a bio-sourced material that delivers a comfortable, lightweight fit without sacrificing durability. The frame is thicker and more structured than injection-molded plastic, giving the Outer Limits its characteristic bold stance. A fold closure keeps the temples secure and the profile clean when stowed.
CR39 Polarized Lenses
CR39 is the optical-quality lens material of choice for premium sunglasses. It cuts glare with a true polarized filter, blocks 100% of UVA and UVB rays via a UV protection coating, and resists impact better than standard glass. The result is sharp, glare-free vision whether you are on the water, on the road, or walking into direct afternoon sun.
Lens dimensions are sized for generous coverage: 54 mm wide by 36 mm tall, with an 18 mm bridge and 145 mm arms. The square shape provides more coverage across the cheekbone than a rounder frame, reducing light bleed from below.
Sustainable from Frame to Packaging
Sito pairs the plant-based acetate frame with equally considered packaging. The Outer Limits ships in a plant-based hard case and includes a microfiber cleaning bag made from recycled water bottles. Both protect your glasses without adding unnecessary waste.
Who It Is For
The Outer Limits is designed for anyone who wants a statement frame that still meets the technical bar for outdoor eye protection. The oversize square silhouette suits a wide range of face shapes, and the polarized CR39 lens is equally at home on the beach, the boat, or a Saturday errand run.
