No Shirt Pocket!
Fit Type: Regular Fit, Color: Blue Stripe, Size: X-Large
No Pocket! The material was nice quality, a little thicker than I would have anticipate for a low priced shirt, and very soft. The only disappointment was there was not shirt pocket. I suppose I did not look closely enough at the photos to notice that before I purchased. Otherwise, this is a very comfortable shirt.

Comfortable soft shirt
Fits great. Looks good too. Very soft fabrick. Thin enough for summer. Buttons are a little difficult to undo. Fabrick is thin around them and feels like it may unweave. Otherwise very well done
