I love this item. They are comfortable, easy to clean, lightweight and have pockets. handy when I travel, car or plane. First I bought two long sleeve shirts, 2X. I'm tall (6ft 6in) and fit well, one of the shirts shrunk after washing. I contacted the company and a few days later I had a replacement. I bought two more short sleeve shirts for the summer. I wear them all the time but especially when travelling.
