Ideal for summer, this short-sleeve has it all: a whimsical tropical pattern, built-in sun protection, sunglass-cleaning patch, and school spirit. This summer shirt delivers great moisture-wicking, fast-drying, UV blocking performance with an all-day UPF 40 rating. A mesh-lined vented back adds breezy comfort. Columbia offers this men's short-sleeved shirt in multiple patterns and sizes. Available in extended sizing. Regular Fit. To ensure the size you choose is right, utilize our 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.
