1. Where can I buy the VBag? 2. How does the VBag work ?
By wriggling the camera into position the polystyrene
pellets inside the V-Bag is forced to fit exactly around
the base of the camera. When you evacuate the VBag it becomes
rock hard and keeps its shape exactly unchanged. The reason for
this transformation from soft to hard is the heavy force that the
pressure differential between the empty inner side and the
atmospheric outside act on the VBag. Also known as vacuum.
3. What is vacuum ?
A vacuum is a volume of space that is essentially empty of
matter, such that its gaseous pressure is much less than

4. What is inside the VBag ?
Inside the VBag you find a custom made net that holds the
polystyrene pellets in place. polystyrene pellets are formed
by blowing molten polystyrene into the air, through a specific
nozzle. The pellets do not absorb neither water nor air. The
pellets are used in other stabilizing products and are popularly
called "Krøyer Pellets" because of the Danish inventor Karl Krøyer.
He used these pellets to lift a sunken ship from the harbour of
Kuwait. The inspiration to this unorthodox salvage method, he said,
came from the Donald Duck story where the clever nephews used table
tennis balls for a similar operation.
5. Why is there two valves on the VBag ?
Well, Murphy's law will say, that you are always on the wrong
side, if there where only one valve. Second, it's a good idea to
prepare the V-Bag before placing the camera. To do this close both
valves firmly. Attach the vacuum pump to one of the valves. Place
the camera; evacuate the air using the pump. If you need to
reframe, just leave the pump attached to the first valve and then
loosen the other valve to let air.

7. Is it possible to use one (or two) VBags to pack a camera insidea carrier bag/backpack etc. safely so it is protected whentraveling across rough country or in an overhead locker in anaeroplane.
Absolutely - we have done that ourselves many times. But - you
should be aware that when used in an airplane, the VBag must first
be acclimated to the pressure in the cabin after take off, which
means you should keep the valves open at take off.
