Great purchase
Size: Large, Color: Blue Shark-white
Shirt was the perfect gift for my 21 year old son. The small pattern was perfect and he said that made the shirt cool. The material is comfortable and light enough for warm weather without feeling cheap. Shirt is versatile with the ability to dress up or down.

Looks great
Size: Large, Color: Black
Looks great, comfortable to wear, love that the buttons are the same color as the shirt, easy to wash, appears to be durably made.
Significantly exceeded expectations (I ordered 2 more).
4 stars instead of 5 because it’s possible to move your arms in a way that makes the shirt slightly tight in the bicep area, but that’s unnoticeable almost all of the time (and minor anyway). Note: even after a couple of wash - wear - wash cycles, there were creases along the same places as where the shirt was shipped; this was easily remedied by a quick iron on a low setting and I think reflects that it is quite resistant to wrinkles.
