David Fusté and Turko Ortiz are two very strong rock climbers with a dream: to push the limits of hard route climbing without ropes. But don't call them free-soloists. No, they are practitioners of a new sort of climbing they like to call deep void soloing or psico BASE. In essence, deep void soloing is route climbing in which your protection isn't ropes, bolts, or cams, it's a BASE parachute. Climbers like Dean Potter have been experimenting with parachutes for years, but these two Spaniards are taking it to new levels. In this episode they head to Monte Brento, in Italy, home to a huge, overhung cliff that is a favorite spot for BASE jumpers but less recognized in the climbing world. Until now.
