Umbro cap, 100% polyester. Size L (57cm). *Although L57cm is listed as being for ages 10-12, it seems to run small. My child, who has an average-sized head and is 9 years old, has outgrown it, so I am selling it. For soccer and futsal. It's lightweight, cool, and doesn't lose its shape. It can be wetted in the summer for use, which is good for preventing heatstroke. ★I bought it, but my child quit soccer soon after, so it hasn't been used much and is in clean condition with no stains. On Amazon, a similar color is sold for around 3500 yen(^^) - Brand: Umbro - Size: L (57cm) - Material: 100% polyester - Model number: UUDVJ003 Thank you.
