Another great Ibuprofen Chapter T-Shirt. This t-shirt is Safety Green so others can see you on the road. Many of our customers who are military need to wear bright colors when riding their bikes on base. The long sleeves will protect you from the sun’s hot rays. Unlike the Black Ibuprofen Long Sleeve Shirt, there is no printing on the sleeves. They are Gildan, Preshrunk 50% Cotton and 50% Polyester.
