Halcyon - Custom Legend MK II Standard Doubles BC System

Standard Doubles BC System

Built for the depths. Ready for what's next. Halcyon helped shape technical diving from the start, beginning with twin cylinders. As pioneers of the backmount systems, we redefined twin-set diving with the Evolve: the first circular dual-bladder system, built for perfect balance and trim.

The Standard Doubles Cylinder System features the Evolve wing in your chosen lift capacity, with an upgrade option to the advanced Legend MK2 for next-gen performance. Ideal for wrecks or cave dives, Halcyon wings ensure streamlined stability and fit, keeping you focused in challenging environments.

ERGONOMIC. EFFICIENT.

The Standard Double Cylinder System begins with your choice of Evolve or Legend MK2 wing, an aluminum backplate with MC Storage Pak, and a secure harness with crotch strap, packed in a Halcyon Traverse bag. Assembly is required, giving you the chance to build familiarity with your gear. Need more control or a custom fit? Upgrade to the Cinchâ„¢ Quick-Adjust Harness, add ACB weight pockets, or personalize your system with custom colors and embroidery.
