This is a cut-and-sew top from Clouded Closet. It's made of suede-like fabric that's smooth and comfortable. It feels like a long-sleeved T-shirt, similar to a sweatshirt, and looks elegant as an inner layer for a jacket. It's the same style as the Men's Bigi Active Tailor series, with a thicker ribbed collar.
