KastKing Hiwassee polarized sport sunglasses are lightweight, wraparound shades with 1.0mm TAC polarized lenses and a durable Grilamid frame designed for active outdoor use.
These sunglasses blend rugged materials with optics tuned for glare reduction and comfortable all-day wear. Built for anglers, drivers, runners, and anyone who spends long hours outdoors, the Hiwassee pair uses KastKing’s PuriVex protective lens coating and a flexible yet resilient frame material so the glasses resist everyday damage while keeping vision crisp.
The Hiwassee lenses are polarized to cut reflected light that causes glare, making it easier to spot details on water surfaces and read contrasts on the road. Polarization lowers eye strain and helps you see shapes, textures, and depth more reliably in reflective conditions.
The Hiwassee frames are molded from Grilamid, a resilient polymer used in demanding industries for its strength-to-weight ratio. That material provides flexibility under stress, resists heat and UV degradation, and maintains shape without adding bulk, while soft nose and temple pads help prevent slipping during activity.
KastKing includes a molded hard case and a Prym1 Camo microfiber pouch for storage and cleaning. The PuriVex coating repels oil, water, and grime, but gentle cleaning is still important to preserve the coating and avoid scratches.
Lens tint influences contrast and color perception, so pick the one that matches your typical conditions. Smoke gives neutral color balance and bright-light comfort; brown boosts contrast for partly cloudy and sunny days; copper enhances depth perception in lower or variable light.
Who is this for? The KastKing Hiwassee polarized sport sunglasses suit outdoor enthusiasts who want performance optics in a durable, lightweight package. Ideal for fishermen, cyclists, drivers, hikers, and anyone needing reliable glare control and secure fit during active days, they offer practical storage and cleaning accessories so you can keep them ready for the next outing.
Q: Do these sunglasses block UV rays?
A: Yes. The Hiwassee lenses block 100% of UVA and UVB and meet or exceed U.S. ANSI protection standards.
Q: Can I wear them for water sports?
A: Absolutely. Polarized lenses reduce water glare and the non-slip pads keep them secure during active boating or fishing.
