Thank you for viewing. This is a babyGap reversible hat (since it's reversible, there's no size label, but I believe it's 50cm, as it's about the same size as the navy hat). The chin strap is made of the same material as the hat and has Velcro. Also included is a navy hat (no brand) size 50cm (the chin strap elastic is stretched out, so you'll need to cut it off or have new elastic attached if needed). - Set includes: 2 hats - Size: 50 cm - Brand: babyGap I try my best to make the colors look as close to the real thing as possible, but the color may look different depending on your monitor settings and room lighting. This is a used item. Please purchase if you understand this. Please be sure to read my profile. I have other items for sale, so please take a look.
