Sims UAP or Unidentified Aerial Phenomena (Unidentified Aerial Phenomena) is a technically advanced snowboard of the All-Mountain / Freeride / Carving type with a high stiffness index (flex 8/10), designed for riders expecting extreme stability and uncompromising performance. Inspired by the legacy of the legendary, iconic Shaun Palmer's UFO model, the UAP model retains the unique features of that design, combining them with the space technology of tomorrow. The board features atomic acceleration and effortless adaptation to changing conditions on the slope – it easily cuts through frozen, hard corduroy, handles bumpy moguls, and when going off-piste, smoothly surfs through deep powder.

• Traditional Camber Profile: A design based on a full, traditional camber perfectly positioned between the snow edge contact points. It generates explosive, powerful pop while guaranteeing surgically precise, unmatched edge hold, and absolute stability during high-speed carves.

• Long Nose Twin Geometry with Symmetrical Sidecut: Although the board's aggressive look resembles a directional model, it is actually a fully balanced twin in terms of nose and tail width. This layout allows for free jumps, landings, and switch riding, eliminating the unpredictability of classic freeride boards. The key element is the extended front of the board (long nose), which provides incredible buoyancy and a surfing float off-piste.
• Dual X Carbon Structural Reinforcements: An advanced matrix consisting of two layers of carbon fiber arranged in an "X" shape directly under the rider's feet, extending to the very ends of the board. This technology dramatically increases torsional stiffness and accelerates response time, ensuring flawless, instant energy transfer from the bindings to the cutting edge.

• MOD 4 Core Wooden Core with Double Bamboo Stringers: Ultra-light and exceptionally lively core being a precisely selected blend of chosen poplar, paulownia, and bamboo wood. Two parallel longitudinal bamboo strips (Double Bamboo Stringers) running along the entire length of the board drastically amplify the core's reaction strength and increase the frame's mechanical resistance to powerful impacts and high-frequency vibrations.

• High-Quality Tri-Tex Fiberglass Laminate: Three-directional fiberglass matrix (woven at angles of 0°, 45°, and -45°) used exclusively in the top competitive models of the Sims brand. Guarantees unmatched, flexible rebound, and precise board feel underfoot.

• Flexible Thin Tip Technology: Three-dimensional thinning of the geometric profile at the nose and tail of the board allows for a drastic reduction in swing weight. This makes this hard monster surprisingly agile in tight turns and easy to control during aerial rotational evolutions.

• Premium Racing Base: A high-performance, sintered base with the highest molecular density, featuring maximum wax permeability and absorption. It guarantees achieving top speeds in any thermal conditions and is exceptionally resistant to mechanical damage.
