Howler Brothers Mansfield Shirt, Tropicalia: Blue Fade. The design of our Mansfield Shirt is simple; a single-button pocket and button-down collar made of lightweight and breathable cotton-poly fabric. But, to separate you from the plaid-adorned masses, we made the Mansfield a platform for our unique seasonal patterns and designs. Features include the Howler signature sunglass cleaning microfiber at the left hem and Howler Monkey icon logo seam tag.
