I’ve had trouble with ear savers sliding down the back of my head, which causes my face mask to shift and the mask straps to pull at the tops of my ears, rendering the ear saver pointless. I needed a knitted ear saver with two straps to keep my mask firmly in place.

The length can easily be customized to fit any size, but because not all masks (or head sizes for that matter) are made the same, I highly encourage you to test this on your mask to ensure the proper tension and fit.
