98% cotton comfort
Color: Black, Size: Large
It's true to size. I have a 42" chest and typically wear a large. I ordered large and it fits. Grab these while you can as most of these mock neck t shirts are a cotton poly blend. These are 98% cotton. This is important because although the cotton/poly blends dry quicker, they are uncomfortably warm if it gets above 70 F. I have purchased other mock turtlenecks and had my local dry cleaners convert them from long sleeves to short, but they are slightly heavier weight than these. I do wish that they made these in a dark green or military green color.

100% SYNTHETIC CONSTRUCTION!!!
Color: All White, Size: XX-Large, Color: All White, Size: XX-Large
When I bought this shirt, the listing claimed it was 95% cotton and 5% spandex... the shirt that arrived was 51% polyester, 43% viscose and 6% spandex! I have been impressed by some of their other clothing, but this is the first time I was completely lied to and bamboozled. I probably wouldn't have noticed if the shirt wasn't so hot, shiny, and uncomfortable! I will absolutely be returning this shirt. Not even CLOSE to what I wanted. Quite, quite disappointed.

Love it
Color: Royal Blue Gold, Size: X-Large, Color: Royal Blue Gold, Size: X-Large
Light and fits perfectly. I bought this size1X for my 14 year old 6 ft3 225lb son. He has a bit of a belly and is kind of built like a football player.
The pants don’t have pockets but they do have an elastic wast with a drawstring which makes a comfortable fit and no need for a belt. The length is perfect for his height and stops right at the ankles to accentuate the shoes.
The top is also perfect for the length of his arms and torso. The sleeves stop a little below the wrist which is great for movement. The neckline is fitted and he can button it all the way up unlike other fancy shirts and without restrictions .
The fabric is soft and the design on the front looks like a very good quality and is very secure.
Over all I’d rate it a 5/5 for quality and fit. I recommend this to anyone big and tall.
