Feels great!
Color: Black, Size: Large
Very comfortable and fitting. The stretch of the fitted fabric is really breathable and the neck part isn’t constricting.

Men's Turtleneck Sweater
Color: Black, Size: X-Large
I really like this turtleneck sweater! The material is soft, warm, and feels high-quality without being too heavy. It has just the right amount of stretch, so it fits comfortably without feeling tight around the neck or sleeves. I’ve worn it both casually with jeans and dressed up — it looks great either way. I order another one in a different color.
