TB Milian Tianyi Wool Knit Short Sleeve TextThe yarn used has a fineness of 68 - this means that each strand of yarn is tightly and evenly twisted. The composition is 80% wool + 20% Tencel. The wool is fine Merino wool, without any rough texture, only as soft as cashmere; Tencel is a plant-based Lyocell fiber, with a hint of cool drape. After being interwoven, the yarn retains the natural蓬松 and rebound of wool, while also having the smooth "flowing" feel of Tencel. When you look closely, there is a layer of extremely fine fluffy halo on the fabric surface, but when touched, it is dry, smooth and slippery - not sticky, and can be worn all year round.
