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.
