The Halcyon Stainless Steel Backplate has been refined to provide the highest-quality finish and materials available. Small details, like the unique bends near the bottom of the plate, create an ergonomic curve, increasing diver comfort. Meanwhile, the precise fabrication process ensures the quality you have come to expect from Halcyon. The utility holes allow easy mating with the optional Halcyon MC Storage Pak to stow an SMB or to fit a drysuit inflation system.
