From Think Tank Photo:
When getting the shot requires extreme body movements, there are few sensations more annoying than having your gear slapping against your chest. To solve this problem, we have released the Backpack Connection Kit
This accessory strap kit is designed to keep the body and lens stored in your Digital Holster
stationary and snug against the torso. Carrying a Digital Holster V2.0 chest-mounted allows rapid access to the DSLR inside it while protecting the camera from dust and damage. The straps of the specially designed Backpack Connection Kit keep the Holster bag and DSLR from sagging or shifting weight during continuous movement.
In the Backpack Connection Kit video
, Kurt Rogers explains how to attach the Think Tank Photo Backpack Connection Kit to a backpack, in order to carry a Digital Holster V2.0 bag on the backpack harness. The Backpack Connection Kit attaches to any Think Tank Photo backpack and the Digital Holster V2.0 series of camera bags.
