Electric Knoxville XL S Polarized Sunglasses
Pickup currently unavailable at BSS
More Coverage, Same Classic Lines
The Knoxville XL S takes everything that made the original Knoxville Sport a standout and scales it up. The result is a large-format square frame that delivers broader face coverage and a bolder look without sacrificing the clean geometry or the precise, comfortable fit that Electric is known for. Designed in California and crafted in Italy, these sunglasses are built for the water, the mountains, and everywhere in between.
Polarized Pro Optics
At the core of the Knoxville XL S is Electric's Polarized Pro lens system. The 6-base melanin-infused polycarbonate lenses block 100% of UV radiation and reduce up to 98% of blue light, protecting your eyes in the harshest on-water and open-sky conditions. The polarization layer eliminates up to 99.9% of glare, so you can read the water surface, spot obstacles, and track movement without squinting or eye strain.
Every Polarized Pro lens ships with a full coating stack:
- Hydrophobic coating -- repels water droplets and spray so the lens clears instantly
- Oleophobic coating -- resists fingerprints and salt residue
- Anti-reflective coating -- eliminates rear-surface glare for relaxed, fatigue-free vision
- Flash-mirror coating -- reduces incoming light intensity and adds a performance-ready finish
- Scratch resistance -- keeps the optical surface clean over seasons of active use
The melanin infusion is not a tint layer applied on top -- it is built into the polycarbonate itself, giving the lens a natural, soothing quality that reduces eye fatigue and produces true color perception rather than the color shift common in conventional tinted lenses.
Grilamid Frame and Fit System
The frame is molded from 6-base grilamid, a lightweight, flexible nylon-based material used across performance eyewear for its resilience and low weight. At just 31 grams, the Knoxville XL S stays comfortable through full-day wear without pressure points on the nose or temples.
Performance-grip rubber is integrated into the nose bridge and temple tips, keeping the frame firmly positioned during active movement even when sweat or water are present. The double action hinge system flexes in two directions rather than one, accommodating a wider range of head shapes and reducing hinge fatigue over time.
Construction and Provenance
Electric designs its frames in San Clemente, California, drawing from the surf, skate, snow, music, and art culture of Southern California. Manufacturing happens in Italy, where optical-grade production standards apply to every step from injection to final coating. The combination means the Knoxville XL S carries the aesthetic DNA of an action-sports brand with the build quality of European eyewear manufacturing.
Every pair ships with a microfiber cleaning bag and is covered by Electric's lifetime warranty.

Frequently Asked Questions
- Are the Electric Knoxville XL S sunglasses polarized?
- Yes. The Knoxville XL S uses Electric's Polarized Pro lens system, which delivers 99.9% premium glare reduction. The lenses also provide 100% UV protection and block up to 98% of blue light.
- What is the difference between the Knoxville XL S and the original Knoxville Sport?
- The Knoxville XL S is a scaled-up version of the original Knoxville Sport. The frame is larger, offering more face coverage and a bolder look, while keeping the same clean square lines, grilamid construction, and Polarized Pro optics.
- What does melanin-infused mean in the Electric Knoxville XL S lenses?
- Melanin is built into the polycarbonate lens material itself rather than applied as a surface coating. This gives the lens a natural light-filtering quality that reduces eye strain and preserves true color perception, similar to how natural melanin in the eye protects against bright light.
- Are the Electric Knoxville XL S sunglasses good for water sports?
- Yes. The Polarized Pro lenses eliminate surface glare from water, the hydrophobic coating sheds spray instantly, and the performance-grip nose bridge and temple tips hold the frame securely during active movement. The 100% UV protection is essential for open-water and beach conditions.
- What lens coatings do the Electric Knoxville XL S sunglasses have?
- The Polarized Pro lenses include hydrophobic, oleophobic, anti-reflective, flash-mirror, and scratch-resistant coatings in addition to the polarization layer. This full stack protects the lens surface and maintains optical clarity across a wide range of conditions.
- Do the Electric Knoxville XL S sunglasses come with a case?
- Each pair includes a microfiber cleaning bag. The microfiber material is safe for cleaning the coated lens surface without scratching.
- What warranty do the Electric Knoxville XL S sunglasses carry?
- Electric covers the Knoxville XL S with a lifetime warranty.
