A longtime partner of the shark-tagging project OCEARCH, Costa has introduced three new frames with shark-inspired colors and a new gray silver-mirror lens. Sales proceeds will go toward expedition funding. The styles include Half Moon, Rincon and Remora; new frame colors include a Tiger Shark pattern. Half Moon features blue- or green-mirror glass or polycarbonate lenses. Rincon's large, square lenses (in blue- or green-mirror) provide total coverage; Remora features a slightly rounder lens shape and will be available in gray or the new gray silver-mirror lens. Half Moon and Rincon start at $249; Remora starts at $189.
