Size
Color: Navy Blue, Size: 3X-Large
love the shirt and they fit well for an overweight man. All the ones I got are consistent in size and you don't see that often.

Excellent style and quality for price
Color: Grey Blue, Size: Medium
Very nice quality and affordable price. Fabric is soft and smooth, very few wrinkles after washing and drying and easy to iron. Seems durable for machine washing and drying. Fits true to size.
