The design, which combines multiple complex Aran patterns, exudes an air of mature sophistication and doesn't look childish even with earflaps. Made of 100% acrylic. Compared to wool, it has less cold resistance, but its smooth texture won't irritate your cheeks or chin. It's suitable for everyday cold protection and fashion. The chin strap is made short so it won't drag on the ground when you squat. It's recommended to leave it untied normally, and tie it with a simple knot in strong winds or when riding a bicycle. I also use the same one, and it makes even small errands enjoyable and fun with a fashionable feeling! Head circumference: Approximately 58-60cm, free size Chin strap: Approximately 19cm (including fringe)
