Seaside sojourns call for equipment that can handle the rigors of water, sun and salt. This hat will have your head covered. Full brimmed for sun protection and light in weight, it's made of a polyester ripstop fabric that is both long lasting and drying. The crown features a window of mesh that's great for ventilation in hot climates. The hat can be scrunched up for packing, and there's foam in the brim, so the hat floats. When the wind blows strong, the Shoreline can be cinched down at both the crown and the chin strap (both have toggle adjustors).
