You will need to double check though as some have different release mechanisms. The premise is simple enough, a sliding hook allows greater freedom of movement for wave riding. Lots of the top pro’s are using sliding spreader bars they have made themselves and so the Dakine engineering department got to work to create this.
It has been upgraded from last years version with a new Kevlar reinforced strap, this reduces the wear and tear on the webbing which holds the sliding hammerhead hook. The webbing can be tightened, which is great as it gives a little after a couple of uses and it can still be easily replaced if you wear through it.
