I was looking for an accessory pouch that could hold my Nikon Speedlight and other accessories so that they would all be in one place and easy to get to. The f-stop accessory pouch large size is able to do that for me. The large pouch is well made with dividers that can be rearranged. The padding in each section is thick enough to provide protection and each section zips shut.
The size is just right for it to be placed above the ICU unit in the backpack.
