The Au Sable 55 offers the same clarity and performance as the 57, but in a slightly smaller, tighter fit for anglers who prefer a more compact frame. The TAC polarized lenses cut glare with the same precision, revealing fish movement, seams, and structure in challenging light.

A lightweight PC frame, metal hinges, and a balanced 55‑17‑139 fit make them comfortable for all‑day wear. The frame is finished in Dark Ale — a deep amber‑brown tone that blends naturally with river environments and pairs cleanly with your outdoor kit.

Built for anglers who want premium clarity in a smaller profile, the Au Sable 55 is tuned for real use on the water.
