Packed into a lightweight backpack, the portable and fire-resistant escape system can easily be stashed in a closet. So when sh*t hits the fan, and you have no other way out but down through a window, you simply strap it on and attach the cable to a secure anchor point (radiator, sturdy desk).
Once you exit, it'll automatically lower you at a speed of around two meters per second via a built-in auto-braking system. Think of it as a knotted bed sheet rappel line devised by Jason Bourne. Or as a bed sheet to sneak out of your parents' house. Either way, picture it working really well and lowering you down safely.
