This product was designed with the objective of protecting its users from infectious respiratory diseases. The materials used in this mask consist of an outer layer of soft, 4-way stretch bamboo viscose for extra comfort and better fit, supported by an inner layer of durable fine stretch cotton. Our unique combination of bamboo with cotton provides both protection and breathability. Bamboo is known for its softness, moisture-wicking capabilities, as well as antimicrobial properties. Your double layer mask features a filter pocket, allowing for you to add a third layer of optional protection. Your filter serves as an added protection and is not reusable. This mask features a simple elastic that is placed around the back of the head and crown of the head, as well as an adjustable wire over the nose. Elastic may be cut and readjusted if desired.
