The K2 Antidote is a high-performance unisex snowboard from K2, designed for experienced riders who move between freeride and freestyle. It combines the stability and precision of a Camber snowboard with features that make it highly versatile for jumps, natural features, fast lines and demanding terrain. The A1 Core combines Aspen, Bamboo and Paulownia for low weight, response and durability, while the ICG™ 20 Triax Glass with Carbon increases pop and stability. The SpaceGlass™ 2.0 technology in the tip and tail reduces weight and enhances edge pressure, while Recess3D reduces swing weight and vibration. The characteristic 3 mm 3D Base Contour helps provide smoother turn initiation and improved handling in soft and variable snow. The construction is completed with Hybritech™ Construction and a Wax-Infused Sintered 4001 Base, providing durability and fast glide. The Antidote is designed for Freeride, Big Mountain, Freestyle, Powder, Piste and Speed and is intended for Advanced – Expert riders.

Binding Information
Compatibility: The board features 2 x 4 Inserts and is compatible with corresponding snowboard bindings.
The insert pattern allows stance adjustment according to the rider's preferences.
Twin Directional Camber – Precision and ResponseThe Combination Camber provides direct energy transfer, pop and strong edge hold.
Combined with the Antidote's Twin shape, it creates a balanced platform for freestyle and
freeride riding, offering precision through turns and stability at higher speeds.
A1 Core – Lightweight and Dynamic CoreThe A1 Core combines three types of wood: Aspen, Bamboo and Paulownia. Aspen forms the main wood of
the core for increased response and pop, while Bamboo is positioned at a 30° angle beneath the feet
for greater durability and improved energy transfer from edge to edge. Lightweight Paulownia in the tip and
tail helps reduce swing weight.
ICG™ 20 Triax Glass with Carbon – Pop and StabilityThe ICG™ 20 Triax Glass with Carbon combines triaxial fiberglass with Carbon reinforcements. The construction increases
pop, liveliness and board stability without adding unnecessary stiffness.
SpaceGlass™ 2.0 – Low Weight and Improved Edge HoldSpaceGlass™ is a lightweight, high-strength fiberglass insert used in the tip and tail.
It reduces weight at the outer sections of the board, helps reduce swing weight and increases edge pressure
at the contact points. The construction also helps reduce vibration and improve stability.
Wax-Infused Sintered 4001 Base – Speed and DurabilityThe Wax-Infused Sintered 4001 Base uses a high-performance sintered material that retains wax for
longer. It provides fast and smooth glide with increased durability, even in demanding snow conditions. The base
also features a Stone Finish for improved glide performance.
Hybritech™ Construction – Low Weight and DurabilityThe Hybritech™ Construction reduces unnecessary material in the tip and tail and uses 3D shaping of the
construction to reduce weight and swing weight. The design maintains high durability and stability without
adding unnecessary material to the board.
Recess3D – Reduced Swing WeightRecess3D removes material from low-stress areas of the board. This reduces
swing weight and limits vibration in the tip and tail while maintaining the structural strength
of the board.
3 mm 3D Base Contour – Smoother Turn InitiationThe 3 mm 3D Base Contour creates a slight three-dimensional curve in the board's base, which moves
snow away from the edges and makes turn initiation easier. The design helps the Antidote move more smoothly through
soft and variable snow while maintaining predictable handling on harder surfaces.
Carbon DarkWeb™ – Response and StabilityCarbon DarkWeb™ uses Carbon reinforcements that extend outward from the insert areas at a
45° angle in an X pattern. The construction increases the board's response and stability at different speeds.

K2 provides a rider weight range for each available length. For the Antidote, the recommended rider weights range from 54 to 104+ kg, depending on the length. Final size selection should take into account the rider's weight, height, ability level, snowboard boot size and preferred riding style. The W versions feature a wider waist and are suitable for riders who need additional clearance for larger snowboard boot sizes.
