I've now bought two of these hats as they are so practical and handy!  I love that they roll up and therefore have taken them on several trips.  They fit great in my purse as well, so I can bring one along wherever I am going.  I also like that they are completely adjustable, so that I can put them on a little tighter or looser, depending on how windy it is or the angle of the sun.  I've branched out now and bought other hats from this company also since I fell in love with these.  I think they make great quality hats.
