I was most excited to try out the Unity Spreader Bar System. Webbing and straps are fine, but when a harness fits the same every single session with no variation, you've got something special. The Unity Spreader Bar Systen and the Crbon Elite V8 delivered. It was easy to get my harness into that sweet spot every time. It's easy and not at all time consuming to adjust. The only issue is once you have the harness on and are hooked to a kite, there are no on the fly adjustments. Land your kite and then you can adjust the size of your harness. This really isn't a huge deal once you have the proper fit.
The harness is super comfy, but the backplate is larger and does slightly restrict my mobility. I've loved it on every session and haven't noticed it until I went kitesurfing and tried to ride toeside for awhile. In general, it is a comfortable harness that is easy to put on and use.
