I love this shirt but just have too many so my wife tells me LOL. Measures 23 inches across the chest and 31 inches long. 

From their website - Featuring a mesh lining and vented back,the World Wide Sportsman Ultimate Angler Short-Sleeve Shirt for Men is perfect for keeping your cool on the water. This breathable fishing shirt has a button placket for easy on and off, as well as additional ventilation. This men's shirt also provides UPF 50 sun protection.

I love the Marlin logo
