67% cotton, 17% viscose,16% polyester. Ridged twill fabric . One size fits all . Here we have the unobtrusively-named Bucket Hat from Folk. Made from some ridged twill stuff that feels even better than it looks, this is the kind-of thing we can imagine some seedy gunrunner from a George V. Higgins novel wearing while skulking round the backstreets of south Boston… in other words, pretty close to perfect.
