The mask uses a soft and stretchable fabric that helps it adhere on the face, and reduces the gap so as to block dust invasion. High quality 3 layer knitted cotton cloth made good breathability, and sweat-absorbing and pollen, dust collection efficiency. Sweat absorbing helps prevent fogging up glasses without needing a valve filter.
