Good shirts
Color: Black Diamond & Dots, Size: Large
Nice shirt. Pattern true to pictures. True to size unless you're 6'2 and you want to leave the shirt untucked, it's a bit short.

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. :)
