Selecting the correct harness is essential to comfort and control while kiting. It is the link between you and the kite, and the point at which the power is transferred from the kite to you. There are four main types of harnesses: waist harnesses, vest harnesses, seat harnesses, and built in shorts harnesses. There are advantages to all of them so it is important to take your build and abilities into consideration when purchasing your harness.
Waist harnesses are perhaps the most common type of kiteboarding harness out there on the water. When a waist harness fits properly it can be very comfortable and allow a large range of motion. A waist harness keeps your arms completely free, making it easier to throw a variety of tricks. Although waist harnesses can be awesome with the proper fit, i know from experience how uncomfortable they can be when they are the wrong size. With the wrong size waist harness it will ride up to your armpits. Waist harnesses are still a very good option, just make sure you order the correct size so you can have a blast out there on the water.
Vest harnesses are a great option for the beginner rider. They offer protection and floatation, and some provide a better center of balance against the kite for beginners. If you are buying a set up to learn how to kiteboard vest harnesses are a perfect way to go.
Seat harnesses utilize essentially the same system as waist harnesses, but they are shaped so that they wont ride up. They also fit slightly lower on the body, causing the kite to pull you differently. Many people find seat harnesses to be a more comfortable alternative to waist harnesses.
Some companies such as Dakine have created a harness system that is blended into a pair of board shorts. The intention behind this design is to integrate the technology and performance of other harnesses with the style and comfort of board shorts. This new idea spreads the pull of the kite throughout the shorts, and removes the need for sometimes bulky harness systems.
