For sale: an Ex Officio Buzz Off Cape sun hat, size S/M, recommended for a head circumference of 22.875" or up to size 7-1/4. I find it has quite a bit of stretch and will go a bit larger. 100% nylon fabric, weighs 2.8oz on my scale, item number 3151-0469. I hand washed in Tech Wash so it's clean ready to go, in excellent condition and showing only light use. $15 including US shipping and PayPal fees.
