This hooded layer combines 64% merino wool with synthetic fibers to create a versatile winter inner layer suitable from city wear to mountain trekking. The 5A-grade antibacterial treatment prevents odor and bacterial growth, while the unique cross-groove knit structure wicks moisture and maintains comfortable temperature regulation during activity. The hooded design provides head-to-neck coverage against cold and wind, with elastic cuffs and hem that offer flexible fit while preventing wind infiltration.
