This is a standard sun shield hat from devirock. I bought it 1-2 years ago. 54cm Navy (It seems they don't have this color this year) UV cut, sunshade, water-repellent, festival hat Kids' hats, UV protection The lining is mesh, and it comes with a stowable sunshade guard, making it comfortable to wear even on hot days. It's also a great feature that it uses a material with a UV protection rate of 90% or more to protect your child's skin from daily UV rays.
