Amazing fit. High quality. Versatile look
Size: Medium, Color: 01-black
This sweater exceeded all expectations. The material is top notch and feels like a much more expensive product. Its not too thick as the sweater can easily be worn with a jacket or coat without being too bulky or hot. It's perfect for those crisp fall days as it will keep you warm even without a jacket. And the fit is exactly as the images suggest. It's an athletic/slim fit sweater that looks great with either dress pants or with a nice pair of jeans. I ordered it in black and red.

Great, stylish and warm mock turtleneck sweater!
Size: Large, Color: Grey
Bought this sweater, because — living down South — I didn't have many winter clothes. But I was kinda shocked by just how NICE and well-made this mock turtleneck was! Very soft, extremely-well fitting and perfect for casual/dressy-casual outings, I've gotten compliments every time I've worn it... and no one EVER compliments me on my clothes! 😄
I love this sweater so much, I ended up buying a second one in a different color... even though I'll probably only need to wear it once a year!
