Parafoil and Sled Kites, are very convenient kites to pack and take anywhere.  Parafoils are completely soft (no spars) and fit in a travel bag, or some of them even fit in a pocket.  You can have them out of the bag and into the air in no time.  They are very easy and reliable fliers. Sizes vary a lot and some of the Mega-Sleds need an adult (or two) at the reins!  These can be great kites for living you line laundry as well.
