OMNI-SHADE: Be safe and protected. Omni-Shade 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. OMNI-WICK: The ultimate moisture management technology for the outdoors. Omni-Wick 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. FRESH AND DRY: This vented shirt is designed for hot weather action, from its advanced UP-40 sun shielding technology, to its quick drying, sweat wicking fabric that includes an antimicrobial treatment, keeping you dry and fresh during active days. DURABLE STYLE: This button down classic cut shirt is made from ripstop polyester and includes a shirttail hemline with button secured multi-purpose chest pockets. BUILT TO LAST: Columbia’s attention to detail is what sets our apparel apart from others. We use only the highest quality materials, expert craftsmanship, and durable stitching. This is a long-lasting shirt you will enjoy for seasons to come.
