Splitboard

Weston Gnarnia Splitboard 2026

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.

Product Details

Laminates

Tri-Axial Fiber GlassMulti-axis, stitched fiberglass laminate that offers a precise and responsive ride in any ­terrain or snow conditions.

Carbon Fiber Stringers2x Tip to Tail + S Weave

Sidewalls

PolyurethanePolyurethane 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.

Base

Sintered Durasurf 4001The 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.

Splitboard Binding

Karakoram Ultra Ranger ​+ Split Interface Splitboard Bindings 2026

The Karakoram Ultra Ranger + Split Interface Splitboard Bindings are built for riders who want to charge hard, go light, and own every line. With a featherweight Carbon Nyolite chassis, cushy EVA footbeds, and ESP damping, your feet stay stoked whether you're skinning up or smashing through chunder. Active Joining tech locks your board together for max edge hold—so go ahead, hit that windlip like you mean it.

Product Details

Tour Mode

Smooth Touring PivotIndependent sleeves rotate freely on a fixed thru-axle, similar to a bike axle, making these stiff and smooth. They're wide for touring rigidity, they shed snow well, and the quick-releasing bracket allows for simple transitions.

Dual Ride StrideSaving energy in the backcountry can be the difference between going for a second lap, going for a longer tour, or going home because you’re wiped out. All Karakoram splitboard bindings come standard with Dual Ride-Stride forward lean. With a -8° forward lean setting, Stride Mode allows you to stride and glide further with every step. Dual Ride modes allow you to effortlessly switch between railing carves and surfing turns. Drive Mode consists of a preset user-adjustable forward lean (0°-22°), and surf mode can be activated without unstrapping (11° or 0°). Simply turn and go. Dual RideStride is the fastest and easiest forward lean adjustment available.

Dual-Speed Riser with Heel Lock Pole Basket FlipFlip up/down with pole basket on the fly. Retractable Heel-Lock included.

Ride Mode

Active JoiningNo slop with instant response. Pre-loaded contact points create an ultra solid connection between your bindings and splitboard.

Ride Mode 3.0Lighter. Better. Faster. Stronger. A smaller footprint with less material makes the Ride Mode 3.0 the lightest splitboard interface. More clearance for snow makes Drop-On changeovers better and faster. Active Joining pulls your splitboard together and keeps your feet spring-loaded to the board, giving you direct power transfer to the edge and instant response in a way that passive, slip-fit puck splitboard systems cannot.

Seam LockPatent pending cove and bead seam lock eliminates seam movement underfoot in all directions.

Direct Power TransferWide binding contact = power transfer directly to edges & tip to tail.
