The elastane in the fabric ensures that the Protective & Reusable ViralOff Face Mask adapts perfectly to the shape of the tank top's face and does not slip even during strong movement. The Protective & Reusable ViralOff Face Mask is washable, does not absorb odors and can be worn several times. It is not suitable for use as a medical protective mask in hospitals and medical professions.
