Then we come to the UDT. It’s the largest mat we can make within the parameters of our tooling. In effect, it’s our XXXL model. The UDT is for very large mat riders, over 250 pounds. Or large riders wearing thick wetsuits and icebergs floating in the lineup. Or average sized surfers who want an uber-mat for micro conditions. Or for anyone who just wants to have fun bouncing around in the ocean with plenty of air underneath them. Or surfers who want to introduce their young’uns to the ocean while tandeming on a mat.
