KLAY is distinguished by a universal fit with performance and protection features that double as design treatments commonly found in many of Kaenon's best selling styles. Designed in California and made in Italy out of injection-molded TR-90, Klay is a wrapped, 8-base frame with tall temples for element protection from sun, wind, water and dirt - then tapers aft into flexible and comfortable temple tips for all-day use. Buried Variflex nose pads further comfort and performance attributes no matter what your activity or use. Powerful, custom-engineered internal cam-driven hinges come standard, as do the SR-91 polarized lenses in G12 and C12 tints housed in Tobacco, Gloss Black and Matte Black frame colors. All at a MSRP of $169 which includes a soft Sport Case and micro fiber cleaning and carrying pouch. Klay is Rx adaptable with SR-91 prescription polarized lenses in Single Vision or Freestyle Progressive.KAENON COLOR CONTRAST:GREY: A neutral tint that doesn't alter color perception.
