Lighter, softer, and with UPF 40 sun protection, the Long-Sleeved Open Air Caster is an update to our popular fishing shirt, keeping everything you love and now with a new eco-conscious stretch fabric and strategic ventilation. Quick drying and incredibly lightweight, our Open Air Caster features thermoregulating MarinoWul+™ made with recycled plastic bottles and crushed oyster shells for earth-friendly performance, and is treated with OutSmart® Fresh odor control to keep you feeling fresh for more time on the water (and less laundry). New, low-profile ventilation is thoughtfully placed to add extra airflow where it’s needed at the back shoulders, arm holes, and chest. UPF 40 sun protection fends off harmful rays with an extended collar stand and slightly articulated cuffs for extra coverage at the back of the neck and hands. Roll-tab long sleeves convert to short for when the day heats up, and two drop-in front pockets keep small essentials handy with a hidden bungee sunglasses/tool keeper in the right pocket. A zippered chest pocket adds secure storage. Finished with a concealed button-down collar that lays flat in the wind, button-adjustable cuffs, and a hidden sunglasses cleaner in the hem. Active Fit.
