From RRD:

RRD has been the first brand to ever build a specific kite for waves. For our Type Wave launched in 2002, we have kept always an eye on a specific kite that would be designed to excel in the waves.

After the introduction of bow and D-shape kites and new innovative bridle designs, this kite puts together a super short leading edge to maximize turning speed with a bullet proof Dacron body construction specifically positioned on the hi-tension areas of the kite to prevent breakage in the surf.

The new religion MKII goes one step further and introduces more power on the big sizes and improved stability and easier handling on all sizes. The control on any of these kites is EPIC. If you are serious about riding waves you will have no other choices!
