Flexon combines innovative design and modern technology to craft these sleek Collins 600 eyeglasses for men. The rectangular frames are made in flexon metal—a lightweight, titanium-nickel alloy that returns to its original shape after bending or twisting. The straight temples come with comfortable coated tips that widen behind the ears for stability and grip. Distinctive detailing near the brow end and on the endpoints adds elegance. Enjoy the union of style and performance in these impressive glasses from Flexon.
