Versatile army green Mens size medium Gander Mtn button-up shirt with practical front pockets. The sleeves zip off to make it short or long sleeve for all types of weather. The fabric is made with a cooling technology to keep you cool, and dry in the hot summer weather. Ideal for everyday wear. The shirt is a mens medium but it runs big in my opinion. It fits closer to a large. Shell is 100% cotton. The mesh lining is 100% polyester.
