Widely known for intelligent and functional designs, this is rigger Brion Toss' personal harness. This rigging harness functions as a bosun's chair but lets you get higher on the mast than a traditional hard seat. It is impossible to fall out of, and allows utter freedom of movement.
Further, it has a built-in tether, (3) halyard attachment points, two loops for hanging extra gear, and a large multi-pocket pouch for cotter pins, small tools, tape and other incidentals.
This is a very heavily-padded mountaineer-style harness designed for the demands of professional yacht rigging who may spend hours aloft. More comfortable, and for longer, than any other harness or chair we've tried.
