TR-90 Frames

Costa Del Mar’s sunglasses are co-injected with nylon frames to make them incredibly sturdy. Specifically, they use TR-90 nylon, a high-quality material resistant to extreme weathers. This is crucial because boating and sailing typically involve being under the harsh sun for long periods of time. 

TR-90 nylon is also a malleable material that may be molded into a wraparound shape. But this does not mean it is not durable. These sunglasses are guaranteed to be long-lasting and resilient for a long time.

In an effort to reduce carbon footprint and save the environment, Costa Del Mar Fantail 580p has made an initiative to utilize bio-based materials in the construction of its sunglasses. Also called the “Bio-Resin Raw Material Process,” resources such as castor oil from seeds of castor plants, as well as bio-based resin, are used in the production of the frames.
