I agree with John. I too have the Prism Roll Up bag, it's very well designed, with a 2 piece carbon fiber spine for extra reinforcement, 10 kite pockets, each with it's own mesh pocket for linsets, handles, tails and spares. You even get a "fanny pack" with bottom loading zipper.
Roll Up Bag can hold 10 kites in bag sleeves plus an additional 10 kites. Full Length 6 feet.
Bag and also be folded, fo easy transport and/or when you only want to take a few kites to the field.
I can't say enough about this bag, IT ROCKS!
