Boyfriend liked it, however it has a weird fit
I got this for my boyfriend as he is a fan of this brand's clothes. I got him small and I am glad I did. Although it looks fantastic on him because he is him, the sweater is strangely long and has a weird tough material to it. It is not exactly soft to the touch, and it has a weird stretch. It doesn't feel like other COOFANDY brand turtlenecks he owns, so I was surprised at how stiff the material was compared to those. The color is also a bit more orange in person.

Ribbing & AComfortable Fit
I stumbled onto this brand as the sizes & sizing were very accurate.
The ribbed feature is a blessing as it masks, hides, conceals stains & or body imperfections.
I'm a 63 year old grandpa who greets outside in the Midwest at church 50 weeks a year.
The warmth, the longer sleeve's and the high & roll up, roll down turtle neck is super cozy.
The value is, it looks more expensive than it actually was, I have already ordered another in black.
