A backplate and wing (often abbreviated as BP&W or BP/W), is a type of Scuba harness with buoyancy compensation device (BCD) worn by scuba divers. Unlike most other BCDs, the backplate and wing is a modular system, in that it consists of separable components. The core components of this system are:
- A harness, which attaches the system to the diver, and which may support other accessories.
- The backplate, a plate normally made from metal which sits against the diver’s back and to which the diver’s cylinder or cylinders are attached.
- An inflatable buoyancy bladder known as a wing, which is sandwiched between the backplate and the cylinder(s).

Famous quotes containing the word wing:
“Sweet Cupid’s shafts, like destiny,
Doth causeless good or ill decree.
Desert is born out of his bow,
Reward upon his wing doth go.
What fools are they that have not known
That Love likes no laws but his own!”
—Fulke Greville (1554–1628)
