Generalities...

All FOGG dividers are made with high-density foam covered in linen, and attach to the inside lining of the bags via velcro.

To ensure that that they hold very firmly once positioned in the bag, each divider has a broad band of hook velcro stitched down the sides, providing a large surface area of grip...
Even more important, no hook velcro is left exposed to grab at finger cuticles or rip and fray camera straps and other gear

The bigger dividers have soft (loop) velcro strips on one or both faces, allowing smaller dividers to be connected to them, in a modular system which can be adapted for different camera gear...

Cradle dividers: the bigger bags have dividers with half-moon cut-outs, designed to allow 35mm type cameras to be literally cradled - suspended - in the top of the bag.
(For other, different equipment the cradle divider can simply be inverted - turned upside-down - when it functions as a standard, sturdy separator..)

trap-door dividers, which hinge from the side of the cradle dividers, support the weight of the camera body and create packing space underneath for less frequently used equipment....

the smaller dividers, of various shapes and sizes, can be configured in between the others
to make custom compartments for all kinds of equipment....

Sizes of the standard set of dividers for each bag are given on the individual page for each model ...height first, and then width
Measurements are for the padded section of the divider - ie excluding the velcro strip on one or both sides...)

Extra dividers can be ordered seperately to supplement the standard set of any particular model
