All Klint models feature what the brand calls "Reflection Applied Concept," which means that each model's performance characteristics edge contact, flex, running surface, sidecut, etc. are scaled to each available length of that model. Klint claims that this helps adapt those characteristics to each skier's size, weight, and ability. Klint's Pure and Pure ST are both freestyle models, which feature what Klint calls "Punk Rocker" the middle 66% of the ski has camber (2mm at center point), while the tip and tails are rockered. The Pure is the narrower of the two (93mm waist at 189 cm) and is thus better suited to inbounds and park environments. It's designed to be a versatile, all-mountain-capable park ski.
