This mask replaces the thin rope that originally hung on the ears with a wider band. This is also the first mask with a "wide ear rope" design on the mask market. It uses a highly elastic ear strap design, which is in line with Ergonomics, it will not strangle your ears even after wearing it for a day.
The design from a thin rope to a wide band not only makes it more comfortable to wear, but also ensures protection. The thin ear straps can be tightened to tighten the ears, while the wide ear straps can be made tighter and fit the face better.
