Question about Wandrd Prvke Version 3

Thank you, so if I understand correctly, there's something to separate lenses and cameras in this article?
What's the point of buying a camera cube then?

The photo backpack does have a camera compartment inside, with customisable protection built in. It is therefore not compulsory to add a camera cube, but it is possible to add one to maximise space if required. The camera cube is sold separately and can be easily removed using Velcro fasteners, allowing the bag to be used for photo equipment as well as for everyday or travel use.
