YES Greats UnInc Snowboard | 2027

Modern Twin. Historic DNA.

The YES Greats UnInc 2027 is more than a freestyle snowboard — it’s a statement piece rooted in the legacy of YES founders Romain DeMarchi, JP Solberg, and DCP. Featuring artwork inspired by some of the most influential video parts in snowboard history, the Greats UnInc blends heritage with next-generation performance. It’s widely regarded as one of the best carving twins on the market — and once you ride it, you’ll understand why.

At the core of the Greats UnInc is its asymmetrical design philosophy. Toe-side and heel-side turns require different mechanics — your heelside naturally wants a tighter, deeper radius than your toeside — so YES engineered the Asym Twin shape and Asym MidBite outline to match those differences. The heelside sidecut is shorter and deeper; the toeside is longer and shallower. Riding in a centered duck stance, your body’s asymmetry and the board’s asymmetry cancel each other out, making every turn feel equally natural and balanced — regular or switch. The result is a twin that grips exceptionally well on hard snow, carves with authority, and still keeps its freestyle playfulness intact.

MidBite steps the sidecut inward 1.5mm between the bindings — a single long disruption that cheats the effective waist width narrower for quicker edge-to-edge response, while maintaining the wider platform at the tip and tail for pop, float, and stable landings. CamRock 2-4-2 provides camber control underfoot with rocker in the tip and tail for forgiveness and lift. The Torrent Core uses 20% Poplar and 80% Paulownia — lighter than a standard blend, with Paulownia significantly reducing weight while maintaining strength. Air L Carbon Reinforcement runs as a straight stringer of biaxial aerospace carbon fiber along the middle of the board from tip to insert packs, enhancing longitudinal stiffness without adding weight. Forever Flex manufacturing stabilises the flex and rocker profile for the board’s lifetime.

Asym MidBite Technology
The Asym Twin applies a tighter, shorter heelside sidecut radius compared to the toeside, balancing out the body’s natural asymmetry when riding in a duck stance. MidBite steps the sidecut inward 1.5mm between the bindings — a single long disruption that cheats the effective waist width narrower for quicker edge-to-edge response. From your bindings out to the end of the sidecut, the board maintains a wider platform for pop, float, and stable landings. The result is smoother transitions, stronger grip on firm snow, and carving performance that feels intuitive and natural — heel or toe, regular or switch.

Board Specs

Note: The asymmetric sidecut means heelside and toeside sidecut radii differ by design — this is intentional, not an error. MidBite also creates a narrower effective waist width than the spec suggests; riders find the Greats UnInc rides wider underfoot than the waist measurement implies. Boot size is a key sizing factor.

Sizing Tip
The YES Greats UnInc rides true to size but feels larger than it measures thanks to the wider platform at the tip and tail. Use boot size as your primary guide — the width under foot is wider than the waist measurement due to the MidBite sidecut. Size down slightly if you prefer a more freestyle-oriented, nimble feel; stay true to size or size up if you want more carving power and stability at speed. Recommended boot sizes: 149 (US 7–8), 151 (US 8–10), 154 (US 8.5–10.5), 156 (US 9.5–11.5), 159 (US 11–13).
