I knew a bloke that lived in one of these; his wife threatened to divorce him if he didn't stop wearing it to bed. Just so comfortable! The WILKIN Bucket Hat is 100% cotton 12oz washed gravel canvas that is fully cotton lined, so it will soak up sweat like it's going out of fashion. We added a built-in leather hatband and stitched the brim then placed a couple of large mesh eyelets to each side of the crown.
