The Aero 7 Skin + PSP Ski is Salomon’s option for beginners learning how to classic cross country ski. Its S-Cut shape and medium length ensure an easy time as you find control, stability, and maximum confidence on the snow. A classic camber from heel to toe amplifies each kick for an improved glide and accelerated return after kick off. The Densolite core is mostly foam to keep the ski light, and a fiberglass wrap makes up the stiffness. Salomon slapped a SkinGrip+ mohair skin on the bottom of the ski for traction right out of the box.
