Racing up and down towering mountain peaks at top speeds attracts ultra athletic, and maybe crazy, skiers, and it goes without saying that these gluttons for punishment demand a ski that can keep up. If you're a rando racer, ski runner, or even a mountaineer with long distance objectives, the ultralight Dynafit PDG Ski provides the weight savings, durability, and downhill capability you need to get up, get down, and get faster. Named for the Patrouille des Glaciers, the world's most famous skimo race, the PDG is virtually the same as the category leading DY. N. A., but with a slightly less featherlight construction and a correspondingly mellower price tag, so you can afford to, you know, actually use it. Part of Dynafit's Ski Running collection, the PDG Ski doesn't make any bones about prioritizing the ascent. The paulownia wood core and carbon speed stringers keep things light and strong, while a 3D carbon Flex Tip reduces mass while smoothly absorbing impact and dampening vibration for a smooth, predictable ride on icy courses and in choppy snow. There's also light alloy in the tip, which minimizes chatter further and makes sure the skin notch doesn't compromise the tip's stability. The PDG's dual radius technology lets you bomb past squirrely descenders by combining the benefits of a long and stable front radius with short rear radius for nimble handling and precise control during short turns or on icy steeps. The PDG's pintail reduces flotation in the rear of the ski, allowing for more control in soft snow and a more energy efficient body position over the ski, and the traditional camber provides plenty of bite when you're putting in first descents or pushing for the podium.
