This new-concept knit uses 100% of the rare "Suvin Gold" cotton, which accounts for only 0.01% of the world's cotton harvest. Furthermore, the yarn is "strongly twisted" during the spinning process, resulting in a "glossy sheen" and a "smooth, dry touch." Wide Rib and Relaxed Silhouette The semi-oversized silhouette allows for relaxed wear. The ribbing on the neckline is a wide 4cm, adding a subtle design accent. The collar is double-layered for durability. It can be worn on its own or as an inner layer under a jacket. I purchased this online, but I haven't had the opportunity to wear it, so I am selling it.
