Reverse it over the face of the mask. To stow a protective mask, hold it in one hand so the hood is hanging free. With your other hand, fold the hanging-down part of the hood against the side of the mask. Then bring the harness around the side of the mask. Grasp hood, harness and mask all together in your hand, open the mask case and stick it in with the lenses pointed toward the back of the case. (Do it a couple of times and it becomes second nature.) What you do NOT want to do is to spread apart the sides of the mask and shove the harness in there--that will slow you down when you need to don the mask, and getting slowed down when putting on a protective mask could kill you.
