These masks are made of highly adjustable soft knit fabric that makes wearing them effortless. Two layers of tightly knit interlock fabric filtrate the majority of dirt and dust particles, while the stretch of the fabric and its self-binding creates a tight contact with the shape of the face and adjusts to a variety of face shapes and sizes. The self-fabric ear loops are soft and adjustable, providing maximum comfort for the wearer. Four different patterns (yellow, red, blue and black) would give variety to day-to-day wear. The quality of the knit would not distort after multiple washes and would assure longevity of use.
