This is the best mask design I’ve purchased/used so far. The 3D pattern, like a basket on its side, is perfect for hugging the chin and staying over the nose, even while talking. And the elastics aren’t sized yet, so you can tie them to fit you, without cranking on the ears and putting you off on a search for those bands to hold the ear-loops of other designs. Very well done - we’ve ordered more since our first because these are the best around. Worth the wait.
