Seat
The seat, or waist, harness is basically a belt around the waist with extension loops attached to put your legs through. By having the support around the waist and legs, a climber can sit while hanging from a rope line. This can give a climber the opportunity to rest, but is mainly designed for the purpose of support and safety. It allows movement and is a favorite among rock and sport climbers.
Chest
The chest harness goes around the chest and arms. Its purpose is stability. When wearing such a harness, it is difficult to flip upside down and is recommended when having to wear a heavy pack while climbing. This is a good harness to use when mountaineering and is normally used in combination with a seat harness.
Body
The full body harness is pretty much the same as a seat and chest harness combined. It has the same stabilization as a chest harness in that it keeps a climber from flipping. It is perfect for kids that might be insecure or those worried about turning upside down. It doesn't however give the climber as much flexibility as the separate chest and waist harness.
