  • It has a reinforced body to prevent against getting inverted during storms. It can also defend against larger sized hail strikes.
  • The canopy sheet is full of microscopic valve-like pores that don't let water through, but reduce upthrust.
    • On the downside, that reduces your chances to survive a drop, using this umbrella as a wind-break
  • The extension spring in the shaft is powerful enough to hoist a car. There is a counter-spring that remains attached during normal operation, reducing the extension force to prevent injuries, but can be disengaged when you actually need to hoist a car.
    • you want to be careful deploying the umbrella with the counter-spring disengaged, without having it latched onto a heavy object on both sides (which you presumable want to move), or it might hurt
  • The tie-wrap can be removed and used to tie-down other stuff while the umbrella is deployed
  • The end tip has a wide-band microphone, used to sense incoming sonic modulation attacks, for which, the driver in the cap, then drives the whole canopy sheet in a cancelling pattern.
    • DSP in the notch
