Item received not as pictured - beware
Item not as described. The navy version I ordered showed a colored zipper and a print pattern inside the collar in the description but the one I received is solid navy in color. Not what I wanted or ordered. It fit fine and I liked the weight of the material as it is a little heavier than another Maelreg shirt I ordered which had the same description. Be careful when ordering as the color and weight of the material is certainly not accurate.

sleeves long
I'm 5'6" and stocky but the sleeves are too long and slip over to rest half way down my hand. If your 5'9 or taller you will be fine.
