Frame materials & technology

Know what you wear.

Not all sunglass frames are made the same. The material of a frame can influence its weight, flexibility, durability, comfort, performance and overall feel.

At JCSunglasses, we believe customers should understand what they are buying. That is why we use and explore different frame materials for different lifestyles — from fishing and sports to everyday wear and premium fashion.

There is no single “best” material. There is a right material for the right purpose.

The materials, one by one

What each material is, how it feels to wear and what it is built for. The JCS ratings are our own read on each material's purpose, not a laboratory measurement.

TPX

Made for Life on the Water

Ultra-lightLow densityWater-oriented

TPX is an exceptionally lightweight, low-density polymer that is particularly valuable for eyewear designed around aquatic environments.

Its low density makes TPX an excellent material for the development of floating-frame sunglasses.

For fishermen, boaters and people who spend significant time around water, this can provide an important advantage.

Important

Floating capability depends on the complete construction of the sunglasses — including the frame, lenses, hardware and other components. Frame material alone does not guarantee that a finished pair of sunglasses will float.

Key benefits

  • Extremely lightweight
  • Very low density
  • Excellent for water-oriented eyewear
  • Resistant to moisture
  • Comfortable for long periods
  • Excellent for fishing and boating
  • Ideal for floating-frame designs

More than just a frame

The frame is only one part of great eyewear. The performance of a finished pair of sunglasses also depends on factors such as these.

This is why JCSunglasses evaluates eyewear as a complete system, not simply by the name of one material.

  • Polarization
  • UV protection
  • Lens coatings
  • Hinges and hardware
  • Nose and temple grip
  • Frame geometry

The JCSunglasses philosophy

The right material. The right lens.The right purpose.

A fisherman has different needs from a runner. An athlete has different priorities from someone looking for premium fashion eyewear. And a customer wearing sunglasses all day may prioritize comfort above everything else.

That is why JCSunglasses does not believe one material is perfect for everyone. We select and explore different materials according to the purpose of each collection — combining technology, comfort, durability, performance and style.

Our mission is not simply to create sunglasses that look good. We want our customers to understand what they wear, why it matters, and which technology is right for their lifestyle.
