Uses
Some people use a SuperFlex Flap (or even several of them together) to create compartments within their bag or to stop items of photography gear from bumping each other. The SuperFlex Partitions have one side that has fuzzy Velcro® stitched low down, this is for a SuperFlex Flap to attach to. This set up allows for gear to be stored below and some gear above the SuperFlex Flap (effectively using it for stacking).
The Flap can also be used to create 'lids' to SuperFlex Partitions – although this only works if the Velcro® strips on the inside of the bag are at the correct height compared to the SuperFlex Partitions to make this work (this depends on the combination of bag and partition).
Occasionally people use the Flap to stack gear inside a Hadley bag however most of the time they are a bit big for this, but they do work well in a few niche situations.
