The FX84 is the narrowest in Kastle’s Freeski Mountaineering line, developed in coordination with Chris Davenport. It’s also the lightest metal-laminate, sandwich, sidewall construction on the market. It’s built for ski mountaineering, positioned between the light and forgiving LX line and the burly MX. With a single turn radius and phenol sidewall, it’s meant to be a precise tool, but a rounded tail aims to give it a looser, freeridey feel. Dual Hollowtech-oval cutouts in the tip and tail-reduces swingweight. Sold flat.
