I put this shirt on right away. It's breathable, lightweight, stretchy, and well-made. I bought the black one, and the fit is perfect, even though it's polyester. I usually prefer natural fibers, but I love the design and the reduced price, so I bought one. The mock turtleneck is comfortably fitted and comfortable around the neck. The short sleeve cuffs hug the biceps nicely. There may be some negative reviews, but not from me. I just bought another one in navy blue, medium. I tried on the shirt with a sports jacket, a bomber, and three different lightweight zip-up jackets, and it goes well with all of them. I still prefer natural fibers, but I also like the Coofandy brand. I have purchased their shirts made of natural fibers as well. The quality is consistent. I ordered and received another shirt in blue. It's a different kind of knit, but fits like a glove. Soft and stretchy, sleeves fit my biceps, and the color hugs the neck close and gently. These shirts are the best!

Great mock turtleneck sweater at an even greater price!

Color: All Black, Size: X-Large

The short sleeve mock turtleneck sweater is made of a comfortable, quality material and looks good. I’m 6’3” and 240 lbs and the XL was a perfect fit. The price point is excellent and I have had great experience with other purchases from Coofandy so I would highly recommend this item.
