KastKing Polarized Sport Sunglasses for Men & Women — Wrap Design, TAC Lenses & PuriVex Coating

Designed for anglers, drivers, and outdoor enthusiasts, the KastKing Hiwassee blends rugged materials, thoughtful lens technology, and a snug wrap fit to reduce glare and improve visual comfort during active days outside. The combination of 100% UVA/UVB-blocking polarized lenses and a durable, scratch-resistant coating gives you clearer vision and longer-lasting optics without a bulky feel.

How do these sunglasses reduce glare and improve visibility?

The Hiwassee uses 1.0mm TAC polarized lenses that filter horizontal reflected light to cut glare from water, roads, and shiny surfaces. KastKing lenses undergo double decentering testing to limit optical distortion so your eyes don’t strain over long periods.

• Polarized TAC lenses reduce reflected glare for clearer contrast.
• Double decentering test minimizes visual distortion and headaches.
• Available smoke, brown, and copper tints match different light conditions.
• ANSI-compliant UV blocking for 100% UVA/UVB protection.

What makes the frames durable yet comfortable for extended wear?

Frames are made from Grilamid, a high-performance polymer used in medical and military gear for its strength, heat resistance, and light weight. The material flexes under stress and returns to shape, so the sunglasses stay comfortable without breaking or warping.

• Grilamid construction for impact resistance and lightweight comfort.
• Tacky nose and temple pads keep the glasses from slipping during activity.
• Wrap design offers secure fit for sports and active movement.
• Heat and UV resistant to hold shape in changing conditions.

How does the PuriVex protective coating help maintain lens clarity?

KastKing’s PuriVex PROTECTIVE COATING repels oil, water, and dirt while providing scratch resistance designed for marine and outdoor environments. That coating makes cleaning easier and helps preserve optical clarity longer than uncoated lenses.

• Repels oil and water for faster, streak-free cleaning.
• Marine-grade scratch resistance for rougher outdoor use.
• Reduces risk of surface damage from everyday wear and transport.
• Recommended cleaning with microfiber to protect the coating.

What accessories come with the sunglasses and how should I care for them?

Each pair ships with a molded hard case and a Prym1 Camo microfiber pouch for cleaning and storage, giving protection on the go. Proper care keeps the coating and lenses performing: rinse with fresh water, gently dry with microfiber, and avoid abrasive towels or saltwater submersion.

• Molded hard case for impact protection in bags or boats.
• Prym1 Camo microfiber pouch doubles as a cleaning cloth.
• Clean with fresh warm water and lint-free cloths only.
• Avoid saltwater immersion and abrasive paper or towels.

Who is this for: The KastKing Hiwassee suits people who need dependable polarized eyewear for fishing, driving, cycling, or general outdoor recreation—anyone who wants strong UV protection, reduced glare, and a comfortable, secure fit without sacrificing lightweight durability. Choose smoke for very bright conditions, brown for enhanced contrast in mixed light, or copper for improved depth perception in lower light.
