Built for the biggest lines. Tuned for the longest missions.
The Gnarnia Carbon Splitboard is our high-octane upgrade to the already versatile Gnarnia - designed for big mountain senders, dawn patrol addicts, and anyone who wants maximum performance with minimum weight on the skintrack. We took our trusted freeride shape and infused it with a high-response carbon layup, plus a featherweight core to create a splitboard that’s light on the uphill, yet locked-in and powerful on the down.
Crafted with the same directional shape, setback stance, and moderate taper as the standard Gnarnia Split, this carbon edition floats with ease in deep snow while staying composed in technical terrain but where it really shines is the construction. The Strike Split Core blends paulownia and poplar with aluminum stringers for strength and snap without excess grams, while Bamboo Inserts boost torsional rigidity for edge hold you can trust when things get steep and spicy.
It’s finished with all the splitboard features Weston is known for - SplitTech edges for uphill grip and tail-shifted balance for easier kick turns, a Rugged Topsheet for long-term durability, Full Perimeter UHMW Sidewalls to protect against rocks and rough transitions, and Skinlock System compatibility for smooth transitions. Like everything we build, it’s rider-tested and guide-approved, backed by our 4-Year Warranty and Board Slayer Program.
If your ideal day includes 4,000 vert before lunch and a technical descent under headlamp, the Gnarnia Carbon Split is your new ride-or-die.
