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
Rocker Type
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
Flex Rating – Sizes 147-151 | Flex 6/10 // Sizes 154-166 | Flex 8/10
Shape
Tapered Directional Shape
Core
Wood Core – Paulownia / Poplar / Bamboo
Laminates
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
Sidewalls
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.
Base
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.
Aluminum Tip + Holeless
Topsheet
Castor Bean Based Rugged Nylon Topsheet

Terrain
Splitboarding A splitboard snowboard is built specifically for the backcountry rider. Splitboards are designed to break down into two separate halves for touring and uphill travel (with climbing skins). Special bindings are required as well. Once you've reached the top of the terrain feature, you reconnect your splitboard for the ride back downhill. However, it's important to note that you will need appropriate backcountry tools, knowledge of the backcountry, weather and snow conditions and climbing skins to safely take advantage of the freedom of a splitboard.

Ability Level
Intermediate-Advanced Whether you’re a progressing intermediate exploring new runs and terrain, or an accomplished rider seeking new thrills, the majority of skiers and snowboarders fall into this level. Intermediate to advanced skis and snowboards may be somewhat wider or stiffer than beginner-intermediate skis and snowboards, usually with a stronger wood core and sandwich sidewall construction. Intermediate to advanced boots and bindings range from softer flexing freestyle options to stiffer choices built for stability at speed.

Rocker Type
Rocker/Camber/Rocker Rocker/Camber/Rocker shapes seek to give you both hard-carving edgehold on firm snow from camber underfoot with enhanced turnability and float in powder from the rockered tip and tail. This profile is increasingly popular for freeride boards designed primarily for soft snow.

Flex Rating:
Stiff

Flex Rating
Stiff The amount a snowboard flexes varies significantly between boards. Snowboard flex ratings are not necessarily standardized across manufacturers, so the flex may vary from brand to brand. Many manufacturers will give a number rating ranging from 1-10, 1 being softest and 10 being stiffest. Here at evo we have standardized the manufacturers' number ratings to a feel rating ranging from soft to very stiff. Generally you will find flex ratings of 1-2 as soft, 3-5 as medium, 6-8 as stiff, and 9-10 as very stiff. Flex ratings and feel may ultimately vary from snowboard to snowboard.
