I received this as a catalog gift when I left the hospital around 2022. I had completely forgotten about it, so I haven't worn it much. I had planned to use it when my child entered daycare and wrote their name on the tag, but I removed it. (Actually, the designated hat was distributed immediately, so I didn't use this one.) The sunshade can be attached and detached with buttons. The chin strap is not elastic, but it's made of the same material as the hat and is adjustable in length. Instant purchase OK. Thank you.
