Union Ultra black men's snowboard bindings (2320213)

Every feature of the Union Ultra bindings has been refined to provide maximum responsiveness and control, making them the choice for snowboarders seeking innovation and technical advancement.

Entering the realm of freestyle with Union Ultra bindings, you become the owner of an innovative solution that pushes the boundaries of snowboard binding construction. The advanced asymmetrical S11 ASYM Duraflex ST baseplate combined with unique Molecular Bushings dampeners made of TPE Outsole ensures unparalleled power transfer and exceptional shock absorption. With a flex rating of 6/10, Union Ultra offers optimal softness, perfect for riders aiming to achieve a balance between firm support and flexibility. Their lightweight, weighing only 815 grams, highlights the technological sophistication of the bindings without burdening the board with unnecessary weight.

The technologies used in Union Ultra are the quintessence of modern design and functionality. The heelcup made of 3D forged aluminum with an Astro washer guarantees durability and precise fit. The Forma X ankle strap and TS 5.0 Ultragrip toe strap provide secure and comfortable foot hold, while the ratchet system made of magnesium SLW with a steel base ensures effortless adjustment. The covering disk is made from Non Stick + Extrarip material to prevent snow and ice buildup, which is crucial for maintaining the lightness and efficiency of the bindings. 

Extruded 3D Aluminum
Extruded 3D Aluminum is a specially designed aluminium heel construction that provides optimal heel hold and minimises drag.
Grade 8.8 Steel
The strongest steel available on the market, used in snowboard bindings by Union, among others.
Magnesium S1
Union's special manufacturing process has produced a durable material that is four times stronger than aluminium and half as light. Used in the production of the belt buckle, it ensures longer life and better spring return.
Moleculer Bushing
A new, lighter layer between the base plate and the board used in Union bindings. It is characterised by good resilience and cushioning and also minimises foot, ankle and knee fatigue.
S11 Duraflex ST
Bucket design in Union brand bindings. Provides increased flexibility and rebound for freestyle riding. The six-degree angle allows for a good fit to the boot and fast edge-to-edge response.
S15 Ultra Duraflex ST
The new spoon design of the Union bindings, which has 6 degrees of tilt, so it fits snugly into the boot. The use of mononuclear foam has increased flexibility.
Forma X
Well-fitting ankle straps by Union with a new design. The casing is highly responsive and the soft insole offers comfort and flexibility.
