Surprising
Size: Medium, Color: Light Grey Vertical Stripe
It’s a heavier cotton, but like it very much will wear it in warm temps as well as colder. Was true to size and the small amt. of stretch makes it very comfortable. Shocked at the price,I purchased fully expecting a bit of dissatisfaction.

knocked 3 stars off because no shirt pocket
Size: X-Large, Color: Light Grey Vertical Stripe
Two stars because there's no pocket. Shirt is actually nice otherwise but I was so focused on finding shirts with button-down collars (so my Sony WXB400 headphones don't escape) that I didn't notice these didn't have a pocket. I always carry a fountain pen so I need that, also for my phone if I'm not wearing cargo shorts with a "technology" pocket.
If pockets are important to you, this shirt should suffice. Price is right.

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.
