This popular Barmah Hat is produced from genuine kangaroo hide leather - which is supplied under permit by the Australian government. The brim width is 7cms. It is fully foldable, waterproof, lightweight and importantly gives ultraviolet protection of factor 50+. It has the famous 'Barmah' sweat band for added comfort, and is supplied with a drawstring calico bag. It is available in dark brown only.
When I visited Australia a couple of years ago we went on a trip into the Rainforest in the North. Our guide was wearing one of these hats, and said that he found it ideal as it kept him dry when it rained (and it really rained!!) and also kept the sun off too. What better recommendation can there be?
