It's a soft material. The sunshade was convenient in the summer. I soaked it in oxygen bleach, but the star pattern has stains on the inside around the forehead. It's more noticeable than in the image. It was folded for storage, so there are fold marks. It's 50cm, but I think it has shrunk due to washing. When folded in half and laid flat, it measures about 24.2-24.3mm, but there may be some error. Please understand that there may be oversights. I customized it by hand-sewing a chin strap. The buttons were also added later. The elastic band can be removed as it's hooked on the buttons. The colors may appear different. Please refrain from separate sales and price negotiations.
