They are modified by hand in Portland by the folks at Findlay hats. They have variable laces so you can customize the hat and make it new again. The laces can be loosened to hold the hat firmly on your head when you're crushing a wave, carving up the streets, or catching brook trout in the tributaries of the Cascades. They all have a hidden pocket to hold a little cash, a card, or your license.
The black colorway comes with an elastic clip in the back that's easy to adjust and will keep the hat firmly in place. The fuchsia colorway has a denim underbib, and leather back size adjuster with metal clasp.
These come with a lifetime warranty through Findlay, for any reason. Even your dog (ask me about my dog Harley and leather patches.... - Maxwell).
