Our cooling bandoo is constructed right into our Floppy Hatbandoo to create surround-the-head cooling performance. It's also reversible! The oversized brim meets and exceeds dermatologist's recommended brim size and seniors love the UPF 50+ sun protection. This is not a UPF coating that will wash off. Nope, just our quality cotton fabrics protecting you. This hat offers classic styling and with state-of-the-art cooling performance. All Blubandoo cooling headwear contains our exclusive, high performance, non-toxic polymer cooling crystals made for us, to our specifications, for this exact application. Our cooling crystals evolve into a gel when immersed in water. Within minutes your Floppy Hatbandoo will completely dry to the touch, yet the active gel will remain hydrated and cool the wearer, due to evaporation, for several days before returning to its original crystal state. No refrigeration is necessary and all of our high quality Blubandoos products are reusable and hand-washable time and again.(COLOR-White, Tan)
