The Halcyon Backplate with Cinch Adjustable Harness comes with either a steel or aluminium backplate. The Halcyon’s novel cinch harness kit is factory fitted to the backplate of your choice. Now you can adjust a harness in a flash.

Halcyon Cinch Harness

The Halcyon Cinch Adjustable Harness redefines what it means to dive a backplate, building upon a platform of simplicity while providing unprecedented security and ease of adjustment.

Halcyon developed the Cinch to save divers time and effort while sizing, fine-tuning and resizing diving harnesses.

Now you can change suits or divers and adjust the harness in a flash without compromising the harness integrity or Halcyon’s trademark, continuous webbing.

Adjustments to the Halcyon Cinch Adjustable Harness occur by simply sliding the harness through a unique assembly. You can even easily adjust the fit in or out of the water with a simple push or pull.

If you need a quick way to get out of your dive system or if you regularly change the thickness of your diving suit, Cinch Adjustable Harness will change the way you dive.

The Halcyon Cinch is specifically designed for Halcyon backplates and therefore does not fit all backplates.

Halcyon Backplate

As with most Halcyon products, an immense amount of behind-the-scenes work is required to create a plate we proudly sell.

Halcyon backplates have 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.

Specially designed for mating with all Halcyon and conventional wings, the Halcyon Backplate is available in 3mm Stainless Steel and Aluminum. The utility holes allow easy mating with the optional MC Storage Pak to stow an SMB or to fit a drysuit inflation system.
