335 Camera Bag (Black w/ Tan 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. Designed specially to fit the Delta Sling of the 225, 335 445 and 555 models, the Delta Pocket will provide extra storage space on your Billingham bag. The twin press-stud fastening is helped by the inclusion of a finger space so that it is not necessary to press against the contents of the bag.
