The grandfather shirt originated as a work shirt for Irish working people. Like the Aran sweater, it has now become a classic wardrobe staple. We have several colors of these traditional Irish shirts available, including the versatile blue Grandfather Shirt or the traditional “natural” color Grandfather shirt. Each shirt has a chest pocket, sizing is a generous cut for comfort and effortless Irish country style. A gift for him from Ireland that gets better with every wear.
