Great Quality, 100% cotton, buy 1 size larger. I’m 100% happy!
Size: Large, Color: Black Charcoal Heather Stripe, Pocket Description: Pocket
I will be buying more of these. I knew they were 100% cotton so I bought a large when I normally wear a medium. After I washed it in warm water and dried it in the dryer, it fits perfectly. The cotton is of great quality not thin and flimsy. I expect to get plenty of wear out of this t-shirt. Also, it did not fade. I recommend buying one size larger.

American sizing!
Size: XX-Large, Color: Oatmeal Heather, Pocket Description: No Pocket
These are great t-shirts and fantastic quality for the price. I bought them for my sons. The cotton is thick and nice-looking, the ivory colour is beautiful and it looks a lot more expensive than it is. I bought one for my eldest son and then bought two more (one for each son). The first one I bought has been getting a lot of wear for about three months. I wash it in the machine and line dry it because we line dry everything where we live. It has held up beautifully, has not shrunk, pilled or changed in any way. The only thing, and it is not a bad thing, per se, is that this is REAL American sizing. We are all tall with broad shoulders, and my eldest is a bit heavy. (Around 1m84 and 105 kg, I'm feeling too lazy to convert it online, but probably in the area of 6'1" or 2" and over 200 pounds.) So I ordered 2XL, which is what he wears in most inexpensive brands we get here. But, although he has been wearing it, as he needed cool-weather clothes, it is long in the sleeves and body and also wide. So I ordered him a second one in XL and he will set the XXL aside until he needs it, or gains weight. I would definitely recommend sizing down from what you usually order. But these are great! The Amazon interface seems to be prompting me to address functionality and cut. The cut is very good, although both large and long. I don't really know what they mean by functionality. It's a t-shirt, not ski wear or running shoes! The cotton fabric is nice and thick and soft. It's comfortable. It definitely works, as a garment. Don't know what else to say!
(Just to let you know, I am a real human ordering from overseas. I am not paid or even receiving merchandise in return for this review, although I wouldn't say no if they offered.)

Great quality shirt, Recommend!
Size: X-Large, Color: Charcoal Heather, Pocket Description: No Pocket
This shirt is suprisingly comfortable, thick and fits very well. Not too short & not too long and is good quality fabric that streches with you. It's more than just a generic, thin long sleeve T-shirt. U can wear w/jeans or chinos, it's that nice. I paid 3x the price for designer brands w/logos that are not as nice. Price is right, too!

JUST "SHORT" OF PERFECT
Size: Medium, Color: Black, Pocket Description: Pocket
I have purchased several of these long sleeves with pockets in various colors.
PROS:
First, they are surprisingly high quality for an Amazon Essentials product. The material is thicker than I was expecting. I was looking for a thinner material to wear inside a shirt but I was pleasantly surprised. These are sturdy.
I also liked the fact at the sleeve ends don't have elastic. They are straight open and loose allowing for free movement and it doesn't feel constricting.
CONS:
However, they are all a little short in length. And some colors are shorter than others indicating inconsistency and quality control issues. The burgundy I got was the shortest. Wearing them is a little frustrating as they are always rolling up and drafty especially in cold weather. If they were just an inch or so longer, I would have given 5 stars.

Well made, well fitting shirt.
Size: Large, Color: Burgundy, Pocket Description: No Pocket
I love buying products that pleasantly surprise. This is a well made shirt made with quality fabric. I also like that it fit me perfectly, it's wrinkly resistant and great value for the money. I've brought this awhile ago and it's held up great in the wash. It's one of those causal wear shirts you can wear just about anywhere. Oh, and the part that pleasantly surprised me the most is the fit. It fit so well, people ask if I've been going to the gym or am working out (I haven't). Who knew all i needed was a nice fitting shirt?
