Look at those curves! Featuring Ski Trab's carbon fiber and aramid honeycomb core construction, the DUO Sint Aero ski has an exceptionally lively and responsive ride for an extremely light package. Elastomer-lined 100 CR6 microcrystalline edges produce superior edge hold while delivering a smooth ride. The high molecular density race base improves glide and resists rock damage. The Duo design increases the tip surface area for better float and easier trail breaking, it also integrates with the skin connection to facilitate easier transitions.
