For the man who refuses to get bent out of shape, EasyTwist offers the ET972 eyeglasses (with no clip-on lens). These handsome frames are crafted in lightweight Trilaston, EasyTwist’s nickel-free, hypoallergenic memory metal. Unlike nickel-titanium memory metals, Trilaston retains its elasticity, shape memory, and glossy color, even after heavy wear. The rectangular silhouette is classic and stylish, and the flexible hinges and comfort-coated ear socks help these glasses feel good all day.
