The Vertx coldblack® polo allows users to stay cool while wearing dark colors in the sunlight. Exclusive coldblack® Technology, combined with moisture-wicking fabric, reflects 80% of the sun’s UV rays and lessens heat absorption — resulting in a light, breathable shirt ideal for warm weather. Streamlined design, convenient sleeve pockets for pens and pencils, and a no-roll collar give this shirt a professional look with all the tactical functionality to get the job done.
