How are Evaporative Cooling Caps or hats made?

Evaporative cooling caps or hats are typically made using a combination of moisture-retaining materials, such as hydrophilic polymers or specialized fabrics, and breathable outer layers. The inner layer absorbs water, which then evaporates to create a cooling effect when air passes through the hat. The outer fabric is usually designed to be lightweight and allow for airflow while providing UV protection. Some designs incorporate adjustable straps or vents for enhanced comfort and fit.
