Jacket BCD vs Wing

The signature BCD decision — comfort habits vs trim physics.

A jacket hugs and floats you upright at the surface, which is exactly why rentals use them. A backplate-and-wing puts all lift behind you, trims you flat in the water, and travels lighter after the plate swap. The wing conversion story is real; so is the jacket’s surface comfort for newer divers.
