O'Brien Aquatic Activity Belt

Quick answer: This is a weight system component from O'Brien.

Why it's worth a look

Getting your weighting right is one of the fastest ways to improve trim and air consumption. Bigger divers often carry more ballast, so spreading it across pockets, trim weights or a harness can take real pressure off your hips and lower back.
