I needed a hat to fit my head while wearing a wig! I have severely thinning hair and have started wearing wigs as an option to help my self esteem and to just make life easier. Its been really great, so easy, but it makes your head dimension larger and regular hats for women are way too small. This hat is wonderful for shade, protection and fit. If I’m not using my UV Blocker umbrella, I’m wearing this hat! Great!
