Duo-Protect-System – behind this concept lies a buoyancy aid with a sandwich structure, with a multi-layered design.
The system was developed under cooperation with the German Sea Rescue Service (DGzRS).
On the inside, the buoyancy chamber has a second skin in the form of a tear-resistant foil. This prevents the life-jacket losing its water tightness and it resists punctures.
Its stretchability is different to that of the outer skin of the buoyancy chamber.
Should the outer skin become damaged, the inner foil pushes against the outer layer and thus seals a potential leak again.
