Directional Powder Camber – A large reverse-camber nose provides maximum float in deep snow while traditional camber underfoot provides a reliable edge hold.

Flex Rating – 6 (1 Soft - 10 Stiff)

Directional Swallowtail

91% Poplar / 9% Bamboo – Sustainably harvested, this blend keeps the board smooth and powerful.

Tri-Axe Glass – Multi-axis, stitched fiberglass laminate that offers a precise and responsive ride in any ­terrain or snow conditions.

Tail V Carbon – Carbon fiber from the tail inserts to the tail contact points to provides added edge to edge response and spring in the tail.

UMHW PE – Ultra High Molecular Weight Polyethylene has one of the highest impact strengths of any plastic out there, which means it can take a beating and look as good as new. For additional durability, the tip and tail sections are stitched to the core for a tighter bond.

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.

Rugged Topsheet – Rugged Topsheet - Polymide is eco friendly and made from castor beans. The topsheet is durable and resistant to scratches and scuffs.

Karakoram UltraClips and Active Joining – Karakoram UltraClips and Tip-Locks use Active Joining to spring load the seam of your splitboard, eliminating the rattling shearing, and rolling inherent to passive slip-fit connections. Simply close the lever to lock in the most responsive ride.

Skin Attachments – Tip holes (for Pomoca Z-Clips) and tail notches.

Shifted Touring Bracket Position

Rooted Inserts – The odds of pulling out inserts on a snowboard are about zero, but just to make sure Weston have reinforced all of the inserts areas with precision-cut sheets of flax. This improved durability and naturally dampens chatter. Additionally, flax is a sustainable crop and is good for the environment.

Split Tech – Weston doesn't skimp on their splits. You'll see a full inner metal edge, complete with sidewall and dampening tape. Also, when facing a kick-turn on a steep slope, you want all the help you can get - that's why Weston balance's their splits so that they are tail heavy.

Standard Splitboard Insert Pattern

Hollow Pivot Pins – Made with stainless steel and hollowed out to be 33% lighter than standard pins

Improved ST (Smooth Touring) Mode – Spark injection molds a proprietary thermoplastic over existing aluminum or steel parts in a process called "overmolding," reducing friction and improving durabillity.

ST Whammy Bars – Overmolded plastic blend where the climbing wire meets the baseplate to eliminate stickiness. (Note: not backward compatible with previous Arc, Surge or other older models)

ST Touring Brackets – Overmolded with low-friction proprietary plastic over and through the bracket holes in the aluminum base - strong, smoother pivoting, and lasts 4 times longer than the old brass bushing.

CNC Machined Baseplates – CNC machined baseplates remain solid for max stiffness and durability. All of the baseplate side windows have been partially filled to increase durability and strength

7075 Aluminum Heel Loops – 7075 Aluminum heel loops are thinner and lighter than our standard heel loops while maintaining the required strength.

Pebax® Pillow Line Straps, Ladders and Adjusters – Pebax® is a plastic commonly used in high-end alpine touring ski boots, It is stiff, tough and 20% lighter than the standard material used.

Proven Burton Buckles

Carbon Reinforced Asym Rip 'N' Flip Highbacks – Asymmetrical design features individual left and right highbacks that slope inward matching the rider’s stance / The upper section is flatter for improved lateral mobility / More material at the base for increased longevity and durability / Higher bottom edge won’t snag on boots with crampon welts or soles that wrap high on the heel

Flippin’ FLAD toggles between your forward lean angle and -13° touring position for easy transitions.

Lateral slots for our BD Touring Strap for greater edge control while skinning.

Tool free micro-adjustable from 0° to 22° for complete customization of your forward lean angle

Made with proprietary custom blended materials for improved strength and durability, while minimizing weight.

Requires Pucks for Mounting in Ride Mode – Spark Canted Pucks recommended (available separately)

7075 Aluminum Hardware – A 65% weight savings is found by replacing 7 stainless steel components with 7075 aluminum hardware, custom made in-house

Ready2climb – The ready2climb skin can be cut to a specific ski in just two minutes without any special tools. The adjustable loop can be fixed to any type of ski.

Grip – Pomoca uses a combination of materials and weaving techniques to combine glide and durability with gripping power. Proper alignment and the fiber attachment systems make Pomoca skins very stable under all conditions and for the life span of the skin.

Glide – This exclusive process gives ski tourers extra glide with less effort. This treatment, applied at the end of the production process and to to entire length of the fiber, makes the skin glide and resist moisture more effectively. Skins with Glide offer an effective process for the entire life of the skin, and unique anti-glopping performance.

Safer Skin Light – Pomoca has succeeded in making it's classic Safer Skin membrane lighter. Thanks to finer layers in the membrane, Safer Skin Light is 12% lighter (150g / m² less). Safer Skin Light makes each pair 60 - 75g lighter, while remaining 100% waterproof and providing slightly less wear resistance.
