A webbing harness with shoulder straps, waist belt and crotch strap, supporting a variety of sliders and D-rings for attachment of cylinders and accessories, with or without integrated weighting or separate weight belts, and with or without a back-mounted buoyancy compensator, which may be attached to the harness, or directly to the diver. Cylinders are usually attached to a shoulder or chest D-ring and waist belt D-ring on each side. Additional accessories may include canister lights and clip-on pockets for small equipment. This style of harness may be off the shelf from an original equipment manufacturer or retailer, or home made, as most of the parts are freely available or relatively simple to make.
