Vests were originally an excellent piece of equipment. Some still are. To boost sales, some folks started adding "features." Things like padding, cummerbunds until eventually some divers were looking like the Michelin man. All these "features" actually make diving harder, but uninformed folks think they are nice to have, so they continue to sell. It got to the point where many people think all vests have these "features" and many of those who think about their diving, started using a BP/wing instead. Others simply stayed with vests that dopn't have those "features." Well, a BP/wing is used by many "tec" divers, so it's gotta be cool. If Susy Creamcheese uses a BP/wing, she'll be cool too. Only trouble is, Susy loves her "features." Several years ago, folks started putting those "features" on BP/wings. Anyone want to guess how long it will be before the majority of BP/wings have those cute little "features" that make diving harder?

Oh. I agree. LOL
