This is where the kites live when they are at home - a Triboard Kite Bag bought form Decathlon. Just about all of the kites, apart from the traction ones, live in here (just!).
It has 2 pockets on the side that are useful for lines, winders, pegs and other bits and bobs and a shoulder strap/handles. It looks well made (and in fact looks the same as some others I have seen from different makers).
The only problem is that if I had kites to it's full size it wouldn't fit in the boot of my car!
Cost: About £12 from Decathlon
When I go out flying I normally take this old bag with me - a cheap bag picked up in May 2002 from Paimpol-voiles in France (cost about 6 euros!). It's big enough for 4 trick kites, with the necessary lines stored in it's bag. The zip has been replaced, and I have had to repair the straps once, but apart from that it has done a very good job over the last couple of years.
Cost: 6 euros from Paimpol-Voiles
