Halcyon Aluminium Backplate

Halcyon’s aluminum backplate is a travel-friendly foundation, offering streamlined performance and reliable trim in lightweight form.

Its ergonomic shape is the result of years of refinement. Unique bends at the base enhance comfort, while precise slot placement improves stability in the water.

Each backplate is CNC-machined from high-grade aluminum, then polished by hand to remove sharp edges—combining durability with Halcyon’s signature craftsmanship. Ideal for warm water or travel diving.
