This long sleeve men’s shirt features some of Columbia’s most renowned technologies built for prevention and protection while outdoors. Our signature wicking fabric makes the shirt breathable; the unique fabric works to pull moisture away from the body so sweat can evaporate efficiently and quickly. The fabric also features tiny dots that work to deflect the sun’s rays to keep you cool. Sun protection is featured within the fabric as well, providing UPF 50 sun protection against harmful UVA and UVB rays; this technology in particular works hard to prevent sunburns and long-term sun damage. Lastly, utility features on the shirt makes securing your smaller items easy. Columbia offers our Men’s Solar Chill 2.0 Long Sleeve Shirt in multiple staple colors and size. 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 elbow. 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.”
