This hat works for women too! My head circumference is a little over 22.5'. I was basically in between sizes so I ordered the S/M and it fits very comfortably. It did leave a little mark on my forehead after wearing it all day long, but never gave me a headache like other hats have in the past. I suspect it will loosen and stretch slightly over time, and it will be absolutely perfect. It fits snugly but not too tight or uncomfortable. Light gray color is perfect. Light and neutral, but not at risk of showing every single thing like a white hat would. I feel like I live at football and baseball games for my 3 boys, and hats are a must for shielding the sun.
