Ties that go behind the head keep a mask on much better than do ear loops. When I need a mask to stay on tightly for long periods, I wear these masks. They are also of heavy material that will help keep viruses out!
3 masks made of soft cotton arrived in a lovely drawstring, fabric pouch. Masks fit well over my average sized adult face, and their elastic loops are comfy over the ears. FYI, the masks are reversible, but the length of the ear loops are NOT adjustable.
Would make a nice stocking stuffer. :)
