The exclusive, patented design of the Padded Insert System prevents small items from wandering between compartments, and allows you to pre-load and store Inserts outside the Domke Bag. Preparing for a shoot is as easy as dropping in the Insert(s) you need! All Inserts feature removable outer-wall cushions so you can increase or reduce the padding around your equipment.The 4-Compartment Standard Insert is designed for extra lenses and/or strobe units, spare camera bodies, or accessories.
