Gray children's helmet made of breathable mesh material. I bought this when my child started walking, but I only used it a few times and no longer needed it after they became stable walkers, so I've been storing it at home. The chin strap and head size can be adjusted with Velcro. It's designed to protect not only the back of the head but the entire head. I plan to compress it for shipping. - Color: Gray - Material: 100% polyester (cushioning) - Cushion material: Mesh material Thank you for looking. Baby helmet, head bumper hat, safety goods
