The Knoxville XL: A Decade of Award-Winning Style
A distinct keyhole nose bridge and broad square silhouette define the legendary Knoxville XL. Electric refined an already iconic frame into its larger XL format, delivering the same classic proportions with a bigger lens coverage that suits a wider range of face shapes. This is a frame that has earned its reputation over more than a decade as a brand favorite, and the XL keeps that legacy alive without compromising on comfort or performance.
Italian Craftsmanship, California DNA
Designed in California and manufactured in Italy, the Knoxville XL carries the precision of Italian optical craftsmanship into an active-lifestyle frame. Electric is rooted in the surf, snowboard, music, and art culture of Southern California, and every design decision in the Knoxville XL reflects that heritage. The frame ships with a lifetime warranty, a standard that reflects real confidence in the build quality.
Bio-Resin Frame Construction
The frame is built from lightweight bio-resin, a material that delivers genuine impact resistance without the weight penalty of heavier plastics. The result is a frame you can wear all day in and out of the water without fatigue. The keyhole nose bridge is a Knoxville signature, offering a refined fit that sits naturally without pinching.
Melanin-Infused Lens Technology
Electric uses melanin-infused lenses across the Knoxville XL lineup. Melanin is the same pigment responsible for protecting human eyes from solar radiation, and integrating it directly into the lens material means protection at the molecular level rather than as a surface coating. These lenses also block blue light, reducing digital and environmental glare for sharper, more comfortable vision whether you are on the water, on the road, or in bright midday sun. All lenses deliver 100% UV protection.
Polarized Performance
Polarized lens options in the Knoxville XL cut reflected glare from water, pavement, and snow. For surfers, paddlers, and anyone spending serious time outdoors in South Florida, polarized lenses are a functional upgrade that makes a measurable difference in visual clarity and eye fatigue over a long session. The variant picker shows which lens options are currently offered.
Fit and Wear
The XL designation means a broader, more relaxed fit than the standard Knoxville, with larger lenses and a wider frame profile. The bio-resin construction keeps overall weight low, so the extended coverage does not translate into extra bulk on the face. The keyhole bridge and squared temple tips hold the frame securely without aggressive grip pressure.

Frequently Asked Questions
- Are Electric Knoxville XL sunglasses polarized?
- Yes. Polarized lens options are offered for the Knoxville XL. Polarized lenses eliminate reflected glare from water, roads, and other flat surfaces, making them a strong choice for surfing, paddling, and driving. Check the variant picker for current polarized options.
- What makes melanin-infused lenses different from standard tinted lenses?
- Melanin is the natural pigment that protects human eyes from solar radiation. By infusing it directly into the lens material, Electric builds UV and blue-light defense into the lens at the molecular level rather than relying on a surface coating that can wear off. The result is more consistent, durable protection over the life of the lens.
- Do the Knoxville XL sunglasses block blue light?
- Yes. The melanin-infused lenses used in the Knoxville XL block blue light in addition to providing 100% UV protection. This reduces eye strain in high-glare outdoor environments and during extended screen time.
