Each of these high quality twill shirts is 100 percent cotton and pre-washed to minimize shrinkage. This very durable natural colored shirt sports wood-tone buttons, and both men and women's styles are available in S, M, L, and XL. The men's shirt has a pocket and button down collar. (The small shirt measures 23 inches across the chest between the arm seams, medium measures 25 inches across, large measures 26 inches, and XL is 28 inches.) So, treat yourself, or order some for your grassroots organization.
