Great hat, just a little too big for my head and I missed the return window. Description from the rnnr website: No matter how the sun's rays try to sneak through, our bucket hat has got you covered, literally! The solid build of the brim ensures your face and neck stay shaded. Side mesh panels enhance airflow, keeping you cool. The hat's innovative design directs sweat onto the brim and then towards the back, ensuring you stay dry and focused. Perfect for all-day sun protection and comfort. Measure the circumference of your head where your hat normally sits to see which size below works best for you.
