Both guys and gals enjoy wearing the Bandoobrim...the lightweight, soft brim, reversible sun visor from BluBandoo. Just soak it in water for 5 minutes and it will keep cool for hours, often times for days! Blubandoo cooling headwear contains its own exclusive, high performance, non-toxic polymer cooling crystals. These crystals evolve into a gel when immersed in water. They then stay hydrated and cool the wearer, due to evaporation, for several days before they dry and slowly return to their original state. No refrigeration is necessary and the high quality Blubandoos are reusable and washable time and time again. All Blubandoo cooling products are hand crafted with the finest materials available. Made of 100% cotton, 5 minute high performance crystals. Cooling you while keeping you fashionable is the passion! When you purchase a Blubandoo product be assured you"ll not only be cool but you"ll have a product you"ll be proud to wear for many years to come.
