Every Faction ski we carry. The read tells you how each skis; the numbers let you compare them straight.
A range (e.g. a 97–102 waist, 12.5–20.6 radius) means the spec varies across lengths; sorting uses the default-length value.
Taper is tip width minus waist at the default length — a directional read of shape, not a precise figure. A dash means the manufacturer doesn't publish the tip dimension.
