New COMME CA MEN Made in Japan Antibacterial Reversible Neck Warmer Brown Material: 80% Acrylic, 15% Nylon, 5% Wool Size: F, Inner Circumference 54.0cm, Width 27.5cm Color: Brown This item uses yarn infused with chitosan, which has natural antibacterial properties. It's a sporty item, but since you don't have to worry about how to wrap it, it's also recommended for those who are not good at coordinating with scarves. The color may appear slightly different depending on the light source. Also, please understand that there may be differences due to monitor performance. I have other items for sale, so please take a look if you'd like.
