I spoke with Chris Dales (Parachute Systems owner) yesterday afternoon for over half an hour, and here is the latest on Parachute Systems and their product line and service.
The factory in South Africa is closed. Negotiations are ongoing with a possible new manufacturer for the Vortex harness/container that would be made here in the US (thus removing one of the bigger reasons given by US jumpers for not buying the Vortex). However, COVID-19 has greatly slowed the negotiating process. Chris hopes to have Vortex production resumed in the US by year's end but nothing is certain due to the uncertainties of COVID-19 and the negotiating process. There are no current plans to resume Volt and Hurricane main canopy production, at least not in the US. There's a slight chance of production resuming in South Africa at some point in the future but those plans have a lower chance of panning out compared to the resumption of Vortex production. If canopy manufacturing does resume, odds are that the Parachute Systems Decelerator reserve canopy will not be produced - only the Volt and Hurricane main canopies. Their crossbraced canopy was discontinued a couple of years ago according to Chris.
Some good news - regarding support for the Vortex and canopies, Chris still has the equipment and materials needed to support spare parts which include but are not limited to reserve free bag and pilot chute, main cutaway, reserve ripcord, and line sets for the main canopies. Presumably this is why their website is still up despite the factory being closed.
Later this year I'll try to get an update and if so will post the latest info. Hope this helps.
