Great looking shirt and good value for the money. Depending on your build you may want to order a size larger. I'm 6'4" and 207. I typically wear an XL and ordered an XL. It fits me but is a little snug there is not much room in the shoulders and sleeves or body for that matter. If I were back to my previous weight of 245 with a larger waist I would have to return it and get a XXL.

Runs a little slender

Size: X-Large, Color: Dark Heather

Love the color and print, but the fabric is stiff and feels like a slender cut
