KEY FEATURES – Oleophobic lens coating repels saltwater, oil, and chemicals - Polarized lenses reduce glare - Impact resistant TAC lenses protect your eyes from flying objects - Block 100% of the harmful UVA and UVB rays - Lightweight, durable, and comfortable Grilamid frames. OLEOPHOBIC LENS COATING – Our oleophobic lens coating creates an oil resistant, anti-fingerprint surface that is impervious to dirt, dust, oils, and other particles resulting in a surface that is easy-to-clean and maintains a cleaner lens longer than untreated lenses. 1.0mm polarized lenses are comparable to the thickness you would find on much higher priced sports eyewear. SUPERIOR FRAMES – Made from the same Grilamid material commonly used by the military and in medical applications, our frames are lightweight, extremely flexible, and heat and UV resistant. Grilamid frames are well known for their strength, lightweight comfort, shape integrity, and impact resistance. This ultra-lightweight and malleable material translates to a very comfortable fit. BASE LENS COLOR and UV PROTECTION – Smoke lenses are ideal for bright sunlight with the most realistic color reproduction and also work well in medium light and partial shade. Brown lenses increase contrast and depth perception, ideal for partly cloudy to sunny conditions. KastKing sunglasses block 100% of the harmful UVA and UVB rays and meet or exceed all U.S. ANSI standards. PROTECT YOUR EYEWEAR – KastKing sunglasses include a molded custom hard case for storage and a custom Prym1 Camo microfiber pouch which can be used for cleaning as well as storing your sunglasses. To avoid lens scratches and lens coating damage, clean your lenses with a clean microfiber cloth or lint free cloth and fresh warm water. Never dip them in saltwater or dry with a paper towel.
