A large, Square Rectangular Aviator based on our unique premium architecture makes the Estero a standout pair. With bold proportions, a double bridge and our distinct sculpted nosepads, these frames not only look the part, but are just as comfortable as any pair of Sunskis. The Strong and durable metal frame is made of palladium coated and electroplated SAE 304 stainless steel to handle any adventure you throw at it.Subtle details hint of the aviation it was inspired from, like the filigree pattern around the lens perimeter that mimics the silhouette of a concord airplane, or the sculpted surface on the arm inspired by a wing. The large square lenses provide great coverage from the sun while making you look like you could pilot any plane you walk into.UV Protection:100% UV A/B/400 ProtectionLens Information:All lenses are polarized, block 100% UVA/UVB/UV400 wavelengths and pass FDA basic impact testMaterials:Rilsan G850 (Ultralight) and electroplated stainless steel frameSolid polarization CR-39 lensesStainless steel hinges with lock-tight screwsDesign & Fit:Eye Coverage: HighWrap & Angle: MediumTemple Width: 145mmBridge Width: 21mmLens Width: 53mmSlate: Non-Mirrored, Grey tint, 10% VLT, Base 4 curveForest: Non-Mirrored, Green tint, 11 %VLT, Base 4 curveAmber: Non-Mirrored, Amber tint, 15% VLT, Base 4 curveAll lenses are polarized, block 100% UVA/UVB/UV400 wavelengths and pass FDA basic impact test.Size & Dimensions:Size: LargeWeight Grams (oz): 29.5 grams1.04 ozLens Width (mm): 52.70Bridge (mm): 21.00Arm Length (mm): 137.50Frame Width (mm): 145.23Lens Height (mm): 43.93Faceplate Angle (mm): 81Arm Tip Distance (mm): 107.5
