Product details:

The Men's Open-Air Caster Long-Sleeve Shirt is the lightest, most ventilated fly fishing shirt Orvis makes. Designed for fishing in tropical climates in late spring or summer, this button-up dries quickly and encourages evaporative cooling to help regulate your temperature. The active fit was constructed with casting in mind, so you can move freely while protecting your skin from the sun's harmful rays. A mesh lining and vents increase airflow to release heat, keeping you comfortable throughout the day.
