Start by packing the Aer Rain Cover Medium around the items you reach for most often. Open the cover, stretch it around the compatible bag, and make sure the edges sit securely around the corners before walking into heavier rain.
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.
