Billingham 445 SLR Camera Shoulder Bag - Black with Black Trim The newly introduced TukTop, allows the main zip, with its double pullers, to be tucked out of the way when opened. No matter how heavily you load the front pocket, the Delta sling is designed to prevent the bag from tipping and to reduce any rolling motion as you move. The bags all feature our Five Loop Fixing system so that you can attach the Billingham Back Pack Harness or Tripod Straps. The G4 slip fits neatly into the front pocket of a Billingham 445 or 555 camera bag.
