timeless rounded frame with a slightly squashed top, a sculpted bridge, and a 4-base tajima polarized lens. double-stacked spring hinge on a single axis — the visible mechanics that define the basn5 line. torpedo surface detail accents the temple design across the hinge gap, a signature element carried across every basn5 style.
named for california's iconic coastal highway — the road that never stops revealing what's around the next turn. highway 1 is the frame you reach for without thinking. round, balanced, quiet in proportion. the modernized classic.
