We have no idea whether it will stand up to a strong storm. But we do know that you can bludgeon someone with it as if it were a baseball bat, and the umbrella will remain unscathed. According to its creators, that's important because unlike a baseball bat, you can carry an umbrella anywhere without looking suspicious or "strange." And this umbrella does look surprisingly normal: it weighs just under two pounds but is supposedly as an effective weapon as a steel pipe.
I also wonder why they edited that guys groin in the picture? Maybe he "reeeaaaally like" his umbrella(s).
