My wife and I got a pair of these for walking about in the sun for extended periods. They are just the right size for shade. I use the chin strap to hang it on my back when I need to get it out of the way, or keep it on my head in a stiff breeze. The ventilation in the crown works OK. The surprising part: we (well, she) will get at least one or two compliments a day about them when we wear them out and about. They resist squashing pretty well. All in all, cool hats. (We actually bought spares.)

UPDATE - OK, now this hat is really special. We went to Disney World and Mickey AUTOGRAPHED it! I got a picture of him wearing the hat.
