The Weston Gnarnia Splitboard is your go-anywhere, send-any-line machine—born for big freeride missions from blower pow in hidden bowls to spicy spring couloirs. With its dialed taper and setback, it floats effortlessly on deep days while staying precise and dependable when the terrain gets technical. Built with a carbon-reinforced core, durable topsheet, and all the power and pop you need for the ride down, the Gnarnia Split is ready to crush the uptrack and rule the descent.
Camber Profile | Freeride – Subtle rocker in the nose and tail provide additional float without losing stability. Camber underfoot provides confident edge hold and pop.
Flex Rating – Sizes 147-151 | Flex 6/10 // Sizes 154-166 | Flex 8/10
Tapered Directional Shape
Wood Core – Paulownia / Poplar / Bamboo
Tri-Axial Fiber Glass – Multi-axis, stitched fiberglass laminate that offers a precise and responsive ride in any terrain or snow conditions.
Carbon Fiber Stringers – 2x Tip to Tail + S Weave
Polyurethane – Polyurethane is poured during construction to form a single, unified piece of sidewall wrapping around the entire core for increased strength and durability. Because of this process, it also creates less waste material than other sidewall options.
Sintered Durasurf 4001 – The gold standard in bases. The 4000-series sintered bases have a higher density than other options on the market, and are therefore more durable. Additionally, it absorbs more wax, making for a faster and smoother ride. 4000-series PTEX is usually reserved for only top-of-the-line boards due to a higher manufacturing cost, but at Weston it’s the minimum standard.

Castor Bean Based Rugged Nylon Topsheet
Split-Tech – Shifted Touring Bracket Position
