Multi use double layered neck gaiter can be worn on your neck or head, and then then adjusted into a face mask when necessary. These are adult one size fits most- they do have some stretch to them.
If buying for a husband or child consider the sizing of fabric in the picture and use your best guess. If it looks too small/too big you will have the best judgement.
These will arrive to us around May 5 and will ship to you immediately.
