Keep cool and comfortable with the Vertex Coldblack Short Sleeve Polo. This shirt is the perfect choice for humid, hot weather operations. Even when you're wearing the darkest of colors, you won't have to worry about overheating thanks to Vertex's unique Coldblack technology that reflects up to 80% of the sun's harmful rays. In addition to keeping you cool, the moisture-wicking polyester fabric keeps you dry. Featuring a no-roll collar and fade-resistant fabric, you'll have a professional look even after multiple washes. A dual-welted pen/pencil pocket on the left sleeve and mic tab or sunglasses loop at the base of the placket make this shirt functional on the job as well.
