The newest range of bucket hats are made specifically for me using the same fabric as the breathable WADDAPLAYA shirts.
They come in 2 sizes:
Medium 59-61cm (23-24 inches) circumference around the head
Large 62cm-64cm (24.5 - 25.5 inches) circumference around the head
I've made the brim flexible so you can stuff it in the bag or in your pocket and it will maintain its shape. And the best part is, with a flexible brim, the wind cannot take it off your head.
Stiff brims make hats fit only one size and allow the wind to pull the hat off your head. I've made these ones specifically for myself and my frustrations with standard bucket hats. I must say, they're awesome.
