All Blubandoo cooling headwear products contain non-toxic polymer crystals. To activate your Blubandoo completely submerge it in water for approximately five minutes. While submerging, the crystals within the channels will begin transforming into a gel. As this occurs evenly distribute the gel throughout the cooling channels. Continue soaking until your Blubandoo gel channel is hydrated to a flexible shape. Then, take it out of the water and blot it off the excess moisture. Allow the remainder of the moisture to air dry.

BluBandoo's are hand washable and reusable time and again.

No refrigeration is necessary.
