Frequently Asked Questions?

What makes the Cinch system different from a standard harness?

The patent-pending Cinch Quick-adjust system allows you to rapidly adjust the harness webbing with a simple push or pull, providing a snug fit and easy equipment removal even when switching between wet suits and dry suits.

Why choose a stainless steel backplate over aluminum?

The stainless steel backplate adds 6 lbs of built-in ballast to your dry weight, which helps reduce the amount of lead weight you need to carry on your weight belt or integrated pockets.

Does this system come with a single tank adapter?

Yes, the system includes a single tank adapter to securely mount your single scuba cylinder to the backplate and harness system.

Can I customize the color or add weight pockets to this system?

Yes, the system can be ordered with custom wing and webbing colors for an additional charge, and it can be configured with or without integrated weight pockets like Halcyon's ACB pockets. Contact us for more info!
