Great polos at a great price
Color: Blue/White, Size: Large
Pleasantly surprised at the quality of these shirts. A bit heavier of a fabric then I anticipated but will be perfect for spring and fall. The size (large) was in fact large. :)

A good find
I liked the style of the buttonless collar. I have 3 that have become my favorite shirts because they fit well, the fabric is soft, light and comfortable in humid Florida.
