Bolle STKS 420 Glasses - Transculent Black/Cobalt Flash Polarized

Engineered for individuals navigating challenging terrain, these glasses offer both robust eye protection and exceptional comfort. Featuring a durable construction paired with premium polarized lenses equipped with a CAT.3 filter, they provide effective defense against intense sunlight, minimize glare, and improve visual contrast.

Lenses in the Cobalt Flash shade, with a thickness of 2.2 mm, are crafted from polycarbonate, offering a lightweight construction paired with exceptional resistance to mechanical impacts. The surface features an Anti-Scratch coating to enhance their durability against scratches. With this protective layer, the glasses preserve their functional qualities for a longer period, even during intensive use.

Owing to their polarization, the lenses effectively minimize glare, resulting in a noticeable boost in image clarity. They also enhance contrast and color saturation, providing relief from eye fatigue during prolonged exposure to bright light.

The frame is constructed entirely from recycled polycarbonate, taking advantage of full frame durability. Thanks to advanced manufacturing techniques, the design achieves an optimal balance of lightness, structural rigidity, and a high level of resistance to mechanical impact.

Side shields offer effective eye protection from dust, fine debris, and airborne contaminants, providing enhanced safety in challenging conditions. The ergonomically contoured temples deliver a secure and comfortable fit, minimizing movement when active and significantly increasing long-term wearing comfort.
