K2 Apache Crossfire Ski: So the Crossfire is an ABS sidewall metal laminate construction. This is designed to rip around the groomers. We’ve also got the MOD technology which is the secondary elastomeric core for dampening, MOD Monic technology which is focus mass dampening and the MX binding system which has wider contact points to get this ski on edge faster and to take this 74mm waisted ski ripping down the groomers.
