A knit cap with double folded ribs that create a plump silhouette. The simple and clean design makes it easy to blend in with any outfit and is easy to wear. The length of the ribs can be adjusted, so both men and women can enjoy their own style. This item is perfect for the cold season and gives you a warm feel. Acrylic is a synthetic fiber made to resemble wool, and is characterized by its plumpness, softness, heat retention, durability, and ease of drying. Nylon is smooth, friction-resistant, and elastic, making it as durable as acrylic. Both have low water absorption and moisture absorption, but they are made up for their shortcomings by combining them with wool with high moisture absorption. Please note that this product may transfer color to other objects or change color due to friction when sunburned, sweat or water. Due to the nature of the material, fluffing and pilling may occur. In addition, washing with water may cause shrinkage, color fading, fluffing, etc., and the texture may change. When washing, put it in a net and press it to wash, and do not wash it with other items. Do not use detergents containing optical brighteners or bleach. Do not leave it in water for a long time or leave it wet. Avoid tumbler drying and let it air dry.
