The Jones Ultracraft Splitboard is constructed to slay the seemingly impossible, hard to reach backcountry lines, where every ounce effects the long uphill skin. As such, the Ultracraft Splitboard is nearly a pound lighter about 25% less than the comparable Hovercraft Split, thanks to Jones' top secret Ultra Construction. This construction technique eliminates all excess weight by combining extensive carbon reinforcement with an Ultra ISO Core. Defying the pervasive logic that lighter construction yields a weaker board, the Ultracraft Splitboard's rock solid demeanor is proven by the pros. You'll find its slightly tapered directional shape and Directional Rocker profile enhance float on the deepest days, without sacrificing edgehold or straight line stability. Plus, Mellow Magne Traction along the inside and outside edges enhance its ability to side hill on ascents and carve steep hardpack on the way down. Its brand new Ultra ISO Core shaves weight by combining stringers of ISO Core, which is a foamfiberglass composite, with beech stringers along the edges for beefed up durability. Textreme carbon shaves even more weight, saving 20 30% compared to conventional carbon, but without sacrificing the board's snappy light feel and torsionally responsive flex. Add in a brand new Sintered Ultra Base that's infused with fluoro and paraffin based additives for unparalleled glide and durability in widely variable backcountry conditions.
