I didn't think such a hat existed! I have problems with my eyes which means bright and low light causes me great difficulties. Plus I need to keep my head warm. Conventional hats do the second job, but lack a sun visor so can't do the first. I've even resorted in the past to wearing a woolly hat on top of a baseball cap. Then, Eureka! I found this little beauty. Trouble is, it's not a beauty. Anyone buying this to be hot in the fashion world will be disappointed. I have been told I look a prat wearing it, but my ears and head are warm and I'm not dazzled by the sun, so I don't care. I am delighted with this hat.
