Mini-bungee cords are handy for lashing something bulky, such as a foam pad, to the outside of a pack. Standard bungee cords and KwikTwists are rather heavy, in my opinion.
Incidentally, in the trivia department, where did the name "bungee cord" come from?
It is a corruption of the term "bunching cord" that was used to bunch together crops during harvest.
