In my backpack kit, I usually keep a small amount of non-industrial duct tape, such as “Duck” ™ brand tape. Duck tape is manufactured with a thinner cotton mesh backing. It is more than strong enough to reinforce a diaper’s tapes or to effect repairs but will be much easier to tear with the hands. More industrial duct tapes are made with a fiberglass backing and are very difficult to tear.
One way to keep a small amount of tape handy is to cut off a 6" section and then roll that around a small piece of dowelling or a section of pencil. That will store easily.
