Lightweight sunglasses in Tiffany blue. These are by far the lightest sunglasses I own. I am selling these because I already have a red pair. 【WYNWOOD】WY*121 ALSTECA sunglasses are innovative sunglasses developed in Italy for people who love to travel and lead a dynamic lifestyle. The frames use GRILAMID TR90, which is lightweight yet flexible, has shape memory for resilience, and excellent shock absorption. The lenses use polycarbonate lenses, which are the most commonly used in sports, and are ultra-lightweight plastic with impact resistance, durability, and cold resistance. Weighing only 16 grams, ALSTECA sunglasses are entirely made in Italy, from material manufacturing to assembly and production.
