The District Vision Air––Wear tech is a constructed from a 'hidden mesh' fabric which is breathable and sweat wicking. The material was specifically designed to allow the skin to breathe in intense performance conditions and was tested over a period of 12 months with long distance running teams globally. Our performance outdoor shirts are made in Europe. The top features the District Vision symbol over the front left chest area and mountain artwork by Filip Pagowski spanning across the back. We recommend washing the shirt warm and air drying it so the fabric retains its performance capabilities over time.
