• Washable cloth masks for adults from locally sourced made in USA fabrics
• An opening in the cloth mask for a filtering material to fit inside
• Adjustable Mask Strap: 3mm
• Air Valve: 1pc
• Air Valve is engineered to transport out the exhaled air and make the mask less moisty and easier to breathe through.

The exhalation valve on the mask act as a ventilation system, making the mask easier to breathe through. When you breathe, the valves are transporting out the exhaled air to prevent the mask from becoming warm and moisty. The valves are engineered to only transport out the exhaled air, and not let any unfiltered air to sneak in.
