Wow what a pullover. If I could give 10 stars I would go off of your chest size. Perfect fit and super high quality.

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.
