About this item

• **Lightweight, Durable Frame** – Crafted for optimal comfort and fit, these sunglasses utilize super lightweight Grilamid material, widely used in military and medical settings. The frames are not only lightweight but also highly flexible and resistant to heat and UV rays. Grilamid is celebrated for its robustness, comfort, shape retention, and ability to withstand impacts, making these frames suitable for medium to large head sizes.
• **Polarized Ultra-Light Lenses** – Our polarized 1.0mm TAC (Tri Acetate Cellulose) lenses are produced from premium Japanese and German materials. With a meticulous 7-layer construction, these lenses offer outstanding optical clarity while being ultra-light, durable, and resistant to scratches. The polarization layer effectively minimizes glare from reflective surfaces, enhancing visual comfort, clarity, and reducing eye fatigue.
• **100% UV Protection** – KastKing sunglasses effectively block all harmful UVA and UVB rays that can lead to eye damage, conforming to or surpassing all U.S. ANSI standards.
• **Base Lens Colors** – Choose from three lens colors: smoke, brown, and copper. Smoke lenses excel in bright sunlight, providing the most accurate color reproduction and perform well in medium light and partial shade. Brown lenses enhance contrast and depth perception, ideal for partly cloudy to sunny conditions. Copper lenses also offer excellent contrast and depth perception, particularly suited for moderate to low light environments.
• **Storage and Cleaning** – The package includes a custom molded hard case and a Prym1 Camo microfiber pouch, which serves both for cleaning and safely storing your sunglasses.
