Start by packing the Aer 3-Way Face Mask around the items you reach for most often. Adjust the fit so it sits comfortably on the face, then check that it stays in place when speaking or moving.
Do a quick test pack before relying on it for work, travel, or a gym day. Carry it around the room, open the main compartments, and check whether your phone, wallet, keys, charger, and other essentials are easy to reach. If something feels awkward during the test, move it before your first full day out.
