Ireland, meet the tropics. That's the appeal of our tropical blue Columbia Tamiami short-sleeve shirt with Ireland's flag recreated in an orange, green and white rectangle over the right front chest pocket. This two-pocket casual Irish shirt is made of moisture-wicking, ripstop poly fabric with mesh-lined back vents for warm days, and it has built in UPF 40 sun protection. Sizes for our front-button Irish flag shirt range from small to 2XL.
