Too thin, neck portion too hard to position to sport the classic turtleneck look.
Color: White, Size: Medium
Too thin. The neck won't hold a clean look, the neck portion bunches and double/triple folds and I can't get that cool turtleneck look with it that I had with my first white turtleneck that I loved so much I wore it out. This one doesn't measure up. If you just want this kind of shirt to wear in warm weather it's good for that because it's very thin.

Surprised by what a great sweater this turned out to be!
Size: Large, Color: Navy
I purchased three of these, various colors. I'm 6'1" /160 lbs. (long and lean) and a large is a great fit without being too loose or bulky. Holds its shape nicely for about 5-6 wearings before it starts to stretch out—particularly the turtleneck. I totally ignored the washing instructions and machine-washed (front-loader) all three sweaters with other items in cold water, regular HE liquid detergent, rapid-spin dry, then dried them in the dryer on delicate, lowest temperature setting for 30 minutes. They came out 98% dry and perfectly re-shaped with no shrinkage. The sweater is supple and soft, and warm and comfortable to about 60°F, after which it's a little warm (for me.) I cannot think of any reason to not purchase one: great fit, great look, great comfort, great price.

Love this Sweater!
Size: Medium, Color: Black
Had my doubts, but this sweater is great! The color is great, follow the care instructions, and this sweater will not let you down. Feels great, fits great, no shrinkage, and looks excellent. Does it pill? Yes, expect it, but I also bought the BEAUTURAL Fabric Shaver and Lint Remover, Sweater Defuzzer with 2-Speeds. And it works beautifully not only on this sweater when needed, but also on my winter beanies and other clothes, which now look like new. My advice then. Buy the de-piller and buy this Sweater. I have purchased six, and I love these sweaters, especially now that I know how to best care for and keep them like new.

SEXY BLACK TURTLENECK SWEATER!
Size: X-Large, Color: Black
This is soft, looks amazing on my husband who is a big guy (6’2” @245) so not everything fits all the time. Sleeves are long enough, and the sweater looks great on him. Soft material, nice collar rate 10/10. Will try and get a nice pic of him in it!
