PuriVex PROTECTIVE COATING – Exclusive KastKing PuriVex coating protects lenses from scratches while repelling dirt, oil, and water for easier cleaning and long-lasting clarity. The tough marine-grade coating helps prevent scratches and resists damage in harsh outdoor conditions, making these sunglasses ideal for fishing, driving, and other active sports. OUTSTANDING LENSES – 1.0mm polarized lenses are comparable to the thickness you would find on much higher priced sports eyewear. KastKing TAC (Triacetate) lenses pass a double decentering test to ensure there is no optical distortion which can cause eye strain and headaches. KastKing Polarized reading sunglasses help reduce glare caused by reflected light to improve vision and comfort. PREMIUM FRAMES – Made from the same Grilamid material commonly used in military and medical applications, KastKing sunglass frames are lightweight, extremely flexible, and heat and UV resistant. Grilamid frames are well known for their astounding strength, lightweight comfort, shape integrity, and impact resistance. This virtually indestructible ultra-lightweight and malleable material translates to a very comfortable fit and the tacky nose and temple pads prevent slipping. 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. Copper lenses provide excellent contrast and depth perception, best suited for moderate to low light. KastKing sunglasses block 100% of the harmful UVA and UVB rays and meet or exceed all U.S. ANSI standards. PROTECT YOUR EYEWEAR – KastKing includes 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 cloths and fresh warm water. Never dip them in saltwater or dry with a paper towel.
