2012 Rossignol S7 Barras: Rossignol S7 Skis feature Rossignol’s unique AmpTek ski design concept that combines traditional and reverse camber to deliver more versatility, rebound, boost and ease-of-use than conventional skis. The Rossignol S7 Skis are perfect for backcountry powder but hold their own on-piste and power through the crud. A wood core provides the ultimate response, feel, powder and durability. The Rossignol S7 Skis also feature Rossignol’s WRS (Weight Reduction System) that features patented fiberglass fibers concentrated under food with less density in the tip and tail to maximize the skis’ durability and minimize overall weight.
