Description Fighting your catch in open water or standing waist deep in a mountain stream, the Smith Hookset sunglasses are the ones you grab to see below the surface. Because glare is every angler&';s adversary, we made them with a variety of lens options, all with glare-cutting polarization that enhances contrast and depth perception. Minimal bottom rims keep moisture from pooling up, while no-slip nose pads ensure they stay comfortably in place until the sun sets.
