To shield our eyes from UV rays and pestering gnats, we slip on the KOO Nova Sunglasses before striding onto the trail. The toric lens boosts our coverage and protection without obscuring our peripherals, while the anti-reflective, 100% UV-blocking tech gives us a clear, crisp view of the terrain. From short lunchtime runs to double-digit training miles, the frameless design keeps the fit light, and the rubber temple tips and interchangeable nose pad keep the fit secure, ensuring squint-free coverage that won't disrupt our flow.
