Kata Casket - Studio In The Field
Beat them. Store them safely and securely in the Kata PALMS-2 rolling casket. It will hold three monoblock heads, three stands, folded umbrellas, cords, and reflectors - in short a complete studio light setup. It is padded and armoured on the edges that will hit the ground, and the rolling wheels are extendable to the side for extra satability. Look at the sad pictures - the editorial studio is currently full of people and I have to use the yard... - the casket is a big blue one with the characteristic yellow Kata lining.
If you are a constant user of a field studio, you might elect to replace one of the monoblock heads with a camera and one of the tripod spots with a folding backdrop. Then you can really be portable - everything in one case.
Note that the casket is also big enough to hold earth from your own country if you need somewhere to sleep during the day...
