The cool max t shirts maximize comfort when wearing body armor by increasing ventilation between the skin and the vest. The men’s cool max t shirts are made of the same material that is used by tennis players and other athletes to keep cool and dry during vigorous competition. This fabric removes perspiration from the skin, sending it to the surface of the material. The air then causes the drying effect that cools the body. The cool max t shirts are available in sizes small to extra-large. If you would like more details on apparel or info on how to order, click on our website at www.interamer.com.
