Safety and visibility are at the forefront of this design.

In an out-of-air emergency, the extended hose provides ample room for you and your buddy to ascend safely and comfortably. The pneumatically balanced second stage ensures breathing remains natural and effortless, reducing anxiety in a stressful situation.

The AQUALUNG Leg3nd Partner is an excellent choice for equipping pony bottles or safety stop cylinders, providing a high-performance, independent breathing system for added redundancy. Whether you´re a recreational diver looking to enhance your safety setup or a technical diver needing a reliable stage regulator, the Leg3nd Partner DIN delivers the confidence and performance you expect from AQUALUNG.
