Thanks for t he hint.

We evaluated the Air Save and the SV-2 models.
In our (humble) opinion, the SV-2 is an old design (vietnam era) that doesn't suit our needs - it is not comfortable to wear and the life jacket is not integrated.
The AIr Save pouches and pockets are modular but are not very convenient (and hang from the vest in a peculiar way), we tried the two models for a short period and decided to look for a better design.
