This is a well-built sun hat, and works great for keeping the glare from direct sunlight off your glasses. It looks like something tourists wear on vacation, but check out your shadow while wearing this - Wow! You're a detective from a film noir classic! I did notice some lasting stains from sweat, but for the price-to-value ratio this is a solid five stars. Will update when I finally try hand-washing in cold water if I have any useful insights.
