I brought this hat on a recent trip to Mexico to wear by the pool.  I rolled it up and stuffed in a pocket of my suitcase and it popped right back into shape.  It fit comfortably.  It says hand wash but I washed it with some delicates in my washing machine on the "hand wash" cycle and laid it flat to dry and it came out great.  I came back and bought another one for my mother who has had skin cancer on her nose and I feel better about her wearing this when she's outside doing yard work or just relaxing in a sun chair.  Great hat!
