The patented Padded Insert System. The heart of a Domke Shooter's Bag: Another Domke exclusive, the Padded Insert System organizes and protects your gear with less fuss... and a lot less bulk. Interchangeable, compartmentalized inserts let you custom-tailor your Domke bag to suit any application or equipment combination. And unlike the flat walls, hatches, floors and bridges you find in other bags, these inserts are complete, self-contained storage components. Which means you can move or remove any Domke insert without having to empty it first!
