OTIS and OUTERKNOWN share a goal to close the loop with sustainable style you can be proud to wear. These collaboration frames use Eco-Acetate that’s biodegradable at its end of life, and mineral-glass lenses that are both highly scratch resistant and endlessly recyclable.

Our Eco-Acetate frames are made from renewable resources widely present in nature. Derived from cotton seeds and plant matter, Eco-Acetate is recyclable, biodegradable and eco-friendly. By being biodegradable, it helps close a circular economy, feeding the earth at the end of life for more natural materials to be grown.
