The minimalist back-buoyancy 5 Oceans' rear air cell is made of stretchy BioFlex backed up with bungee cord, enabling it to offer loads of buoyant lift while maintaining a low-profile shape. The BC offers excellent shoulder, waist and sternum adjustments to guarantee the perfect fit. The QLR weight system has sectionalized pouches to accommodate partial ballast loads for warm water. Or, combined with the rear trim pouches, the system will easily hold enough weight for virtually any cold water application. There's a single drop-down zippered pocket on the right side of the rig, a few strategically placed D-rings, plus webbing loops, hose clips, grommets, and a carabiner for attaching loads of gear.

No BC captures the essence of a Dual Purpose BC better than the 5 Oceans. It fit over our bulky dry suits to tackle a winter's day of diving off the California coast, then snugged down to offer a clutter-free fit on a 3mm shorty for a dip in our warm water test pool. The BC is light and packs flat yet still offers over 40 pounds of buoyant lift and 30 pounds of ballast weight capacity. The Bioflex bladder eliminates any "winging" of the air cell. In fact, you feel like it's not even there. With the contoured shoulders and first-rate adjustable waist and sternum straps, few BCs fit as snug or feel as stable at depth. The QLR weight system is one of the easiest to load and ditch, especially now that Aeris got rid of the Velcro backup patch, which was well-intended but just got in the way. The singular drop-down cargo pocket stays out of sight until you need it, then provides a large easy-access place to stow your treasures.

Bottom Line

The 5 Oceans is without a doubt the do-it-all BC for back-buoyancy aficionados. Light and compact for travel with sufficient lift and weight capacity for local submersions.
