Heavier fabric, very durable
Fit Type: Regular Fit, Color: Grey, Size: Large
3 stars. Pretty nice shirt but the fabric is a bit firmer than i like. I iron it when i usually wear it so that it looks half decent since wrinkle resistance is low or poor. I usually have to use a higher setting on the fabric since the material is thick making it alot heavier. Overall great for the lower end cost, anything that beats it would probably be double the price. I work in a cubicle so this works well for me, a simple shirt, with a simple color.

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.
