This harness is great for those who have problems when a harness rides up too far into their ribs or chest area or just having problems wearing the regular harness( great for those with ribs problems and looking to take it easy out on the water). The side ilium panels along with the bottom leg straps allow for great comfortably and take off the added pressure on the ribs that one would have wearing a regular waist harness. Jumping would be the same as any other kite but due to the fact that all the added pressure is switched from your core to your legs or butt area one would have to watch out on the landings... make sure to stick em at all times.
