As in Free Climbing, but using no protective devices whatsoever. Here the climber relies solely on strength, agility, technique and personal judgement. Needless to say, free solo can be very dangerous.
Free climbing without the protection of a rope. A single mistake could easily be fatal, as there is no back-up to secure a climber who slips (see Dead Cat Bounce). It is an extremely dangerous manner of climbing and while many consider free soloist a bit looney tunes, a number of others consider free soloing the purest and most exhilirating expression of the sport. There are good arguments on either side. Of course, here at Touchstone, it is expressly forbidden to free solo, because we care dearly about your safety and well-being.
