SOS Group first approached Extreme Cases to design and manufacture a lightweight, rapidly deployable container solution for their Hyperlite SL3 system. The Hyperlite SL3 is an ASME PVHO-1 Case 18 compliant lightweight single-lock hyperbaric chamber designed for multiple occupants.

Utilising SOS Group’s patented flexible braided tube technology within a bespoke Extreme Cases Lockdown Container, the system was developed to support rapid mobilisation while providing robust protection during transport and deployment.

The resulting solution supports military, medical, and industrial applications where portability, reliability, and ease of deployment are critical.
