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 missions. 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.
I've purchased three of these polls for work back in 2014. Now all three have a two tone appearance. The color and top of the shirts all appear brown from sun fade. It's not just me having this issue it's all of my fellow deputies that I work with as well. It seems that you get about 6 months before they begin to fade in this mannor. They areally nice shirts and areally very comfortable to wear over body armor. And if your used to having a long sleeved button up you will be happy with the breathable material these shirts are made of. My only concern is the sun fade. I paid 50+ $ for each shirt and had them stitched with my departments logos. It cost me about 95$ per shirt. Overall a nice shirt with a simple flaw.
