Nice shirt.
Size: 16.5" Neck 32"-33" Sleeve, Color: Grey Pearl
Quality seems good for price. Fit fine around chest and belly but tight in shoulders and arms.

Good Fit for a Bigger Guy
Size: 18" Neck 34"-35" Sleeve, Color: Vert
I'm a bigger guy--6-foot, 240lbs--so I struggle sometimes with finding the right fit. This shirt fit my broad shoulders and ample mid-section with ease, and I was even able to tuck it in. I have long arms (76-inch reach), and this shirt fit the bill. I liked this shirt so much that I ordered seven colors--enough for each day of the week. After a year, the fabric is still strong and the colors vibrant.
