My Knotty Tie face masks stay in place without adjustment better than any other type of mask I've bought, which is the most important consideration along with material type and number of layers in a mask for me. The around-the-head elastic is so much more comfortable than ear elastics and do not leave me with skin irritation either. The fabric is also soft and comfortable on the face. The large size is the first to comfortably fit my partner's face, and is the only mask consistently worn by him. Cheaper masks are just that...cheap but not worth buying when they neither fit well nor look as good.
