I want to clarify my position. I am not saying folks need to run away. I am saying do NOT trust the marketing materials. Do NOT expect the vest to do the things they claim. Do NOT rely on the vest as a sole source of safety (outside of competition where a standard vest is required).
There are some good folks who have worked on designs but the idea of an airvest has inherent risk above and beyond a standard vest regardless of design or improvement.
