This is a knit hat with a brim for kids. There is no size notation, so I think it's free size. It's knit, so it stretches. I took pictures with a measuring tape, so please refer to them. It has boa on the back and is very warm. I think it can be used by both boys and girls. I didn't use it much and it became too small, so I think it's in a clean condition. If anyone would like to use it, please do. This is a used children's item, so please consider this before purchasing. Please note that it will be compressed for packaging. Pattern/Design: Plain Color: Gray Material: Knit Season: Autumn, Winter
