The KOSKI sweater is carefully crafted from an extra-fine merino wool blend. It features a stand-up collar, rib-knit cuffs and Size for a comfortable fit, and a metal zipper for added versatility. The sweater is made from a high-twist yarn, which not only enhances its durability, but also enables breathability and makes it hygroscopic, capable of effectively managing moisture. What's more, it benefits from water-repellent properties and can be easily machine-washed, remaining wrinkle-free even after numerous washes. The superior quality of this sweater is further enhanced by its machine-washability. The model, measuring 6'1", is Size M for reference.
