This is a casual and cute knit hat featuring a combination of multiple complex Aran patterns in a pleasing color scheme. Made with 100% acrylic yarn. While not as cold-resistant as wool, it has a smooth texture that won't irritate your cheeks or chin. It's suitable for everyday warmth and fashion. The chin strap is kept short to prevent it from dragging 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 hat, and it makes even quick errands feel less of a chore, making me feel fashionable and happy! Head circumference: Approximately 56-58cm (standard size) Chin strap: Approximately 27cm (including fringe)
