Parallel is a minimalist rectangle rimless silhouette made in lightweight, matte black titanium for durability to last a lifetime. Designed with ample, rectangular UV-protective nylon lenses and spring hinges that allow the temples to bend past ninety degrees for improved flexibility and an adjustable fit. The titanium frame will not ever rust, tarnish or corrode, meaning it is biocompatible and therefore non-toxic to living systems. Each pair comes with a branded case, pouch and cleaning cloth.
