Umm, OK.
What do we know about the adverse cases?
Were they really the result of substandard vest performance,
or were the user (or post-facto lawyer) expectations too high?
It's a new material that has an unexpectedly rapid deterioration rate (BP vests do deteriorate and have a finite lifespan, this was just a lot shorter than predicted). Once discovered, SC moved fast to make good by replacing all Zylon vests at no cost. Sadly the lawyers moved in too.
