Im one of those persons who always break my shades and if its not me my kids pretty sure do the job. These ones from Give Three Eyewear seems unbreakable and I like the concept of using on using materials that are not harmful to the environment, they are light and of course the shapes are pretty nice too. There are two unisex models to choose between the Brosewood and Trolleander. 1% of the proceeds will be donated to charity.
