My Mother had recently purchased this identical Booney hat...It made alot of sense.  The previous one I'd been using had the nice wide brim and was linen BUT..it couldn't get WET..you couldn't launder it.  SO you couldn't wear it to the pool..anywhere it was really warm (perspiration), in the rain, or anywhere it might get soiled.  THIS Columbia Booney does it ALL and launders beautifully..is cool,packs nicely in bag/luggage, protects sensitive skin on face, ears etc with its nice wide brim, has chin strap so if it blows off, it is still secured around your neck AND is adjustable!!! I HAD to HAVE ONE and found it on Amazon!  LOVE THIS HAT!
