This is the perfect hat for women! It is stylish, comfortable, and lightweight. It has an adjustable strap on the back to adjust the fit. I bought the grey color with the pink sparkly logo to wear at work to keep my hair out of my face. It’s so comfortable that I forget I’m wearing it. I saw the white color on sale for $10 so I decided to get that one too. It is a quick dry material so it keeps you cool all day long. I highly recommend this hat!

I feel I will love this hat! The fabric is light, soft, and breathable. I bought the color, Wonder Sage, and I love it, it’s very versatile! The hat itself I feel will be cooler to wear compared to a typical ball cap. I light and fits great!
