The airy, 3D mesh material together with the elastic ear loops provide an adaptive fit around your face. For ultimate relieve, install the detachable head-clip to allow for less pressure on your ears. | |SWEDISH DESIGN| Treated with POLYGIENE, a Swedish fabric treatment that permanently protects the outside skin-fabric, making it also much durable. The washable skin and the replaceable filters make this breathable mask forever lasting and more environmentally friendly than classic masks. The Airinum masks are designed in Sweden. | |4 SIZES| Our ergonomic mask shape will fit all face types.
