The RescYou by Mammut is an innovative rescue device in the event of a fall into a crevasse. It can be used to rescue yourself or other climbers. After braking a fall into a crevasse, the device is attached to the climbing harness (self-rescue) or a fixing point (rescue of another person). After this, the two rope clamps are clipped to the rope and the compact six-fold pulley, which connects the two rope clamps, is operated. This allows the person who has fallen into the crevasse to be rescued as quickly and easily as possible.
