This is a North Face Sunshield Hat. Sizes are KM and KS. How about for siblings? I used to have my sisters wear them. They have been used, so there may be a feeling of use, but I took good care of them, so I think they are relatively clean. There are individual differences, so please consider if you don't mind. They will be folded for shipping. Comfortable hat with mesh lining, a combination of camouflage and beige. - Brand: THE NORTH FACE - Color: Beige - Design: Camouflage pattern - Material: 100% polyester - Features: Mesh lining Thank you for viewing.
