The ORCA OR-40 audio-bag harness offers improved weight distribution and reduced fatigue for location sound mixers, sound recordists, and boom operators carrying an ORCA audio bag. It features an internal cable and a dedicated pouch to support a battery or power bank, making it especially useful for demanding shoots.

The OR-40 utilizes an EVA skeleton with mesh fabric to ensure light weight and breathability while the padded back increases comfort. A special sliding system adjusts, so the harness can fit any operator of any size. The OR-40 can be attached to any ORCA audio bag and allows separate use of the top and bottom sections.
