Everything about Union Ultra bindings
Everything about Union Ultra bindings
This binding offers lightweight comfort with ultimate cushioning and pop, perfectly tuned for freestyle snowboard sessions.
Discover the Union Ultra Bindings
The Union Ultra Arthur Longo binding is built for riders who demand maximum board feel and comfort without sacrificing performance. Arno personally finds this binding perfect for side-hits, presses, and park tricks: every movement is smoothly transmitted with minimal vibration and maximum pop. Thanks to the lightweight design (approximately 865 grams), this binding feels playful without making your board feel heavy.
The Stage 11 Duraflex ST baseplate is asymmetrically designed for full torsion and board flex, and in combination with the Molecular Bushing with TPE Outsole, you get cushioning that absorbs shocks and combats fatigue, even on long days on the slopes.
Arno emphasizes the Hybrid 1.0 ankle strap: the Exoframe exterior provides the support needed for presses, while the interior is soft for long-lasting comfort. The TS 5.0 Ultragrip toe strap holds you securely, regardless of your boots, and the magnesium S1 ratchets feel reliable and smooth when tightening.
The binding is designed for freestyle riders, with an all-mountain focus: with a flex of 6/10, it is playful but retains enough stiffness for charging days. Due to compatibility with both 4×2 and The Channel mounting systems, this binding is universally applicable on almost any snowboard. Union offers a lifetime warranty on the baseplate and heel cup, and 1 year on other parts – that gives confidence for intensive use.
In short, according to Arno, the Union Ultra Arthur Longo is a top choice for those who want to combine freestyle style, board feel, and comfort in one binding – without compromises.
