Introduction

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.
