The Knockaround Fast Lanes are lightweight polarized sport sunglasses built for everyday wear, driving, and outdoor activities. They feature polycarbonate frames with embedded rubber nose pads for secure grip during athletic use, polarized lenses that reduce glare and enhance clarity, and UV400 protection against UVA/UVB rays. The lenses arrive with a bonus microfiber pouch that doubles as a cleaning cloth.

Lens & optics: Polarized polycarbonate lenses deliver solid glare-cutting performance typical of affordable-to-mid polarized shades; impact-resistant construction. Frame & fit: Lightweight square-frame design, rubberized accents, fits medium-to-large faces comfortably. Who it's for: runners, cyclists, baseball players, and everyday drivers seeking affordable protection without designer overhead.

Value position: Knockaround is a recognized affordable-to-mid brand in the polarized segment—no warranty mentioned in available data, but consistently praised for durability and comfort relative to price. The $38 price point places it squarely in the budget-friendly category, competing with SUNGAIT and generic rivals rather than premium marques (Ray-Ban, Costa, Maui Jim).
