Packaging designed in a way that you don’t have to use an additional waterproof bag to store it. There are 2 holes on the packaging for air to escape. Simply use a adhesive tape to block one of the hole first then squeeze the air out before blocking the second hole with another adhesive tape. The packing will become air tight, water resistant and more compact, now you can put it into the rear pocket of your jersey.
