This knit cap is made using a seamless whole garment knitting method for a comfortable fit. The absence of seams eliminates bulkiness inside and provides a superior fit. It uses acrylic material woven with far-infrared-emitting ceramic for warmth. The yarn is treated with antibacterial and odor-resistant processing, so you don't have to worry about odors from stuffiness. The folded-over part has a patch logo, making it a versatile hat suitable for both outdoor activities and everyday wear. Fabric: 85% Acrylic, 10% Nylon, 5% Wool Size: Suitable Size (Head Circumference): KF (53-56cm)
