Whether we're looking for a new casting spot or settling in until we get a bite, we wear the Costa Slack Tide Polarized 580P Sunglasses for a clear view. The polarized lenses help us see into the water, and are constructed from polycarbonate for excellent impact resistance. Elements like a ventilated design and the Hydrolite Padding keep us comfortable for a long day in the sun so we can stay out until we catch a fish worthy of showing off in photos.
