The Yuba is an easy-to-wear unisex style that looks good on just about everybody. Consistently one of the top pairs we recommend to our community, the Yuba is a lightweight and versatile style that's a bestseller for good reason.We designed these shades in collaboration with fellow San Francisco outdoor brand Huckberry, and named it after the mighty Yuba river in the Sierra Nevada mountains of California. To us, the Yuba is a state of mind that reminds us of weekend adventures with good friends.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:SuperLight recycled polycarbonate framesSolid polarization TAC lenses (Tri-Acetate Cellulose)Stainless steel hinges with lock-tight screwsDesign & Fit:Eye Coverage: MediumWrap & Angle: LowTemple Width: 140 mmBridge Width: 22 mmLens Width: 48 mmLens specs:Ocean Fade: Fade, Blue tint, 11% VLT, Base 4 curveForest: Non-Mirrored, Green tint, 11% VLT, Base 4 curveTerra Fade: Fade, Amber tint, 10% 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: SmallWeight Grams (oz): 18.3 grams.64 ozLens Width (mm): 48.42Bridge (mm): 22.04Arm Length (mm): 136.49Frame Width (mm): 139.75Lens Height (mm): 42.75Faceplate Angle (mm): 82.0Arm Tip Distance (mm): 100
