Fit is very similar to the V1 driver seat harness. Spreader bar rides slightly lower. This is an improvement for me since I am fairly short. Increases the amount of bar reach so I have a little more depower. Same great range of motion for legs in a seat harness.
Integrated kite knife pocket is excellent. Vast improvement over an add on key pocket. Had a couple scary incidents with kite lines getting caught on the add on key pocket. Integral grab handle in the back is a great improvement over having to add line and tubing to get a grab point added to the V1 harness.
Wings on the spreader bar insert easily into thier pockets. Greatly improved over the V1
Definitely my favorite seat harness ever.
