Whether you're fast like a bee or zippy like a cheetah, the Tifosi Wasp Interchangeable Sunglasses offer paramount protection and maximum visibility. Crafted with an open lens, half frame construction, the Wasp is designed to be compatible with three different lenses that cater to varied terrain, sunlight and adventures. Outfitted with adjustable nose and ear pieces, the frames are constructed with a durable, homopolyamide nylon called Grilamid TR 90 that's known for its low density, high resistance to chemical and UV damage, and incredible bending strength while the Tifosi polycarbonate lenses protect you against harmful UVA and UVB rays with its true polarization that's embedded into the material itself rather than simply coated with a thin layer of polarization treatment. Not to mention, these decentered lenses are also furnished with ventilation and a glare guard, which prevents unnecessary glare and increases airflow, in turn preventing fogging and encouraging optimal visibility.
