Showerspecs are durable, meant to get wet, and are made from premium-level materials. The frames are made from grade A acetate in a choice of Misty Green, Pastel Blue, or Stone Gray. The lenses are lightweight and feature an anti-fog, hydrophobic coating on both sides. The hinges are 5-barrel riveted stainless steel. Since these are going to get wet, we made quality a top priority.
