Harnesses come in many different styles for different outdoor sports. There are also many different styles for a single sport. If you want to, you can buy a different harness for each sport. However, most harnesses can be used for several different sports if you're willing to put up with a little bit of hassle. I own a rock climbing harness that I also use for caving and for canyoneering. It was one of the cheapest ones available and you have to double back the waist and leg straps, which can be very annoying. If I were to go back, I would spend the extra $10 and get the straps that you can just pull to tighten.
