Do they make extenders for these to use in powder?
No, they do not. Tubbs does not offer extenders on there snowshoes. The flex design is made to excel in packed snow and the other design is the traditional design which is made for a variety of snow conditions. This particular model is made to take on steep icy terrain. You might check out a tradition design from tubbs if your going to be in the deep stuff. The other option, if you like this one, is to go with the XL model.
