These masks are fantastic!
So Although these are light and sheer, you absolutely cannot see through these when they are on. A plus there.  They are by far the most comfortable mask I or my children have worn. Husband has the larger one and wants another one.  They are very breathable and I would say probably the most breathable of all the masks we have tried. However, they are still a mask. You can feel a small amount of warmth from your breath but  if you pull it tight you can breathe through it instead.  I wouldn't say that it is the same as a mesh mask but a close second. Definitely a keeper.  I don't know how they made them so soft and stretchy but Thank You!!
