Denim dog hat. The lining is mesh. I think it's a good size for small dogs like Toy Poodles and Schnauzers. I bought it at a pet supply store for about 2,500 yen. My dog doesn't like it, so it's hardly been worn, but I hand-washed it for this listing. Please purchase if you understand that this is a used item. 【Size】 Head circumference: approx. 31cm Ear hole: approx. 16cm Distance between ears: approx. 6cm Brim: approx. 3cm Weight: 19g
