Take on the trail in Columbia Men's Thistletown Park Long Sleeve Crew Shirt. This staple item is perfect for active and casual days because of its comfortable fit and its essential technology. Columbia is renowned for our quality material and proprietary technology featured in our men's apparel. This long sleeve shirt is clean and simple, but its built-in technology packs a punch. This long sleeve shirt features our signature wicking fabric for ultimate moisture management during activity-driven days. The unique technology quickly moves moisture from the skin into the fabric where it spreads across the surface to quickly evaporate—keeping you cool and your clothing dry and comfortable. The UPF 15 sun protection blocks UVA and UVB rays to help prevent sunburns and long-term skin damage. The tight weave construction with UV absorbent yarns block the full spectrum of harmful UV rays. The crew neck and all-way stretch fit make all-day wear and movement comfortable. Our signature logo is featured on the chest for subtle style. Whether you wear this to tackle the terrain, or chose to wear it on a casual weekday, you'll remain protected and comfortable. Columbia's trail shirt comes in many sizes and colors. Extended sizing available. Regular Fit. To ensure the size you choose is right, utilize our sizing chart and the following measurement instructions: 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.
