We purchased this shirt for my hubby to wear to work as a hospital engineer. We bought 3 brands to try and he LOVES this one the most. He says he likes that the shirt has a chest pocket and still looks professional while walking around the hospital. He runs a higher than normal body temp and tends to get hot and sweaty easily. He says the material was breatheable and was very comfortable to work in. Hes 69 270# with a long torso and this shirt in a 3XLT was the perfect length for tucking into his pants.  Though all 3 shirts trialed were a size 3XLT, this one was longer . It fit him exactly like the model in the photo, the sleeves came down to the elbows, etc. We purchased the ROYAL BLUE color and its a really nice color.  The material and color looks like it will hold up after several washes.
