Women’s fit!
Size: One Size, Color: Black/White/3, Size: One Size, Color: Black/White/3
This hat fits women’s heads ( mine is small) and is fully adjustable by the Velcro strap on the back. It is made out of light material that is great for a workout and has air holes / mesh for cooler wear. So eat to clean just pop in the washer and hang to dry! Doesn’t get stiff at all and retains its shape! Very well made & stylish in the black/ white color combination. Great for keeping the sun off your head, or just extra warmth!
