Burton Family Tree Gril Master snowboard celebrates Marko "Grilo" Grilc's passion for both family and snowboarding by making it possible to introduce their own children to the world of snowboarding. It's a snowboard that works just as well for relaxed family rides as for more advanced rides when you're on the mountain yourself. Whether it's big air and slopestyle or the starry sky that shines over the mountains, Grilo's story lives on.
