Collection: Backplate & Wing BCD

A Backplate & Wing BCD is a modular scuba buoyancy system with:

Backplate: rigid metal or lightweight plate that holds the tank and harness
Wing: inflatable bladder behind the diver for buoyancy
Harness: webbing/straps connecting the diver to the plate
Optional STA/weights: tank adapter or integrated trim/ditchable weight options

It’s popular for streamlined trim, durability, customization, and tech-style diving, but it can be less “plug-and-play” than a jacket BCD.
