Typhoon Aloha Polarized Sunglasses 949TBK are designed to fit larger faces with comfortable ease, equipped with a taller frame design, broader temples, and a more ergonomic fit than other large-scale sunglasses. These Typhoon Optics sunglasses feature broad lenses crafted from T90 Grilamid nylon, which is highly durable and resists slippage caused by perspiration. Large, full-frame polycarbonate lenses characterize the sunglasses, which are scratch- and impact-resistant but also lighter than traditional plastic lenses. The Typhoon Optics Aloha Polycarbonate Lens Sun Glasses actively repel moisture with Typhoon Polarized Optics' innovative AquaView advanced hydrophobic lenses, which stops static, stands up to scratches, and lets water roll right off the lenses without leaving smudges or haze behind. Powerful polarization on the polarized sunglasses completely eliminates glare from your field of view, enhancing the vistas you'll see through the Aloha. Get great visual acuity with a splash of style when you wear the Typhoon Polarized Optics Aloha Large Frame Shades.
