A Halvar The Protector Face Mask Extender Strap is a must-have accessory for anyone wearing a face mask for long hours to reduce constant ear strain and pressure caused by traditional face mask over the ear loops. The durable Protector strap is more flexible and holds its shape better than other brand straps, making it ideal for repeated use and long-lasting wear. It's also safe to clean with chlorine or bleach cleansers. The strap hooks onto any face mask's loops and easily adjusts to fit all adult head sizes. Once attached to the mask, you can wear the strap above or under your ears, whichever is most comfortable. Our extender strap is an ideal solution for staying protected as comfortably as possible over long periods. Made in USA. Adult size only. Face masks not included.
