Superflexes partitions are used to seperate equipment inside your Billingham bag. Superflex partitions are 150mm long but vary in width and height according to their number. The dividers are positioned to provide one square comparment. Please note that our inserts are designed to work with the padded base inside our bags.The underlying principle behind our SuperFlex system is simple. When a force is applied to the outside of one of our bags its integral padding absorbs some of that energy. The excess is transmitted to the SuperFlex system which absorbs more of the knock with its own padding and if that is not enough, it will absorb even more by deforming so that its usual square corners become more diamond-shaped. In doing this, all the gear in the SuperFlex system is gently moved aside to prevent it from banging into each other. The SuperFlex then returns to its normal ?square? cornered self ready to protect your kit from the next impact. Fitting could not be easier because all SuperFlex components are located by Velcro touch fastener strips to the bags padded interior and rest on its foam-insulated base.With so many different lenses and other delicate equipment available today, we needed to develop quite a range of SuperFlex models to accommodate them. We think we have come up with a selection of sizes that should cover almost every need, protecting your valuable investment from the worst bumps and bashes.
