The polyester interlock construction of Columbia® PFG Terminal Tackle Long Sleeve Shirt offers full coverage against harmful midday sun with Ultraviolet Protection Factor (UPF) 50. It's also lightweight and quick-drying, making it the perfect solution for staying cool while protecting your skin from any highly reflective water. It's the ultimate day-out-on-the-boat staple... lightweight, durable, go-to gear. Columbia® offers this fishing shirt in multiple staple colors and sizes. Available in extended sizing. To ensure the size you choose is right, utilize the brand's sizing chart and the following measurement instructions: For the sleeves, start at the center back of your neck and measure across the shoulder and down to the sleeve. If you come up with a partial number, round up to the next even number. For the chest, measure at the fullest part of the chest, under the armpits, and over the shoulder blades, keeping the tape measure firm and level.
