Over the past few seasons Völkl has been extending its 3D.Ridge design to encompass almost all of its RTM, All-Mountain and Big Mountain collections. Last year, Völkl significantly upgraded what is now its signature design with the addition of 3D.Glass. An added base layer of prepreg fiberglass hardly sounds newsworthy, but its impact can scarcely be over-stated. The special sauce in 3D.Glass consists of flaps in its center section that fold up and over the sidewall, interlocking the base with the rest of the 3D.Ridge. For an on-trail ski like the RTM 81, 3D.Glass is transformative. When the RTM 81’s long front and rear rocker blend with the camber zone underfoot as the ski is flexed, the security on edge is first rate.
