Mares Back Buoyancy BCD – Streamlined Comfort & Stability for Southern California Diving
This superbly comfortable and stable back-buoyancy BCD is designed for Southern California divers who want excellent trim, freedom of movement, and dependable performance in cold-water Pacific conditions. With 21 kg / 46 lbs of lift, a streamlined profile, and Mares’ proven SLS integrated weight system, this BCD delivers confidence and control from kelp forests to boat dives and travel adventures.
