Union Source Pro Snowboardbinding
The Union Source Pro was developed for snowboarders who accept nothing less than the highest level of performance. This premium binding combines ultralight weight with brute strength and an extremely direct response, allowing you to feel every detail of the terrain beneath your feet. Whether you’re carving at high speed, dropping steep freeride lines, or riding technical descents, the Source Pro delivers an unmatched connection between you and your snowboard.
The heart of this binding is the advanced two-layer baseplate construction. It combines an ultralight Forged Carbon Core with a Duraflex CB frame, providing maximum strength, optimal responsiveness, and exceptional board feel. The result is the lightest baseplate Union has ever developed, allowing you to carry less weight without sacrificing performance. The outcome is a binding that responds instantly to every movement and lets you feel your snowboard in detail.
The highback of the Source Pro is made from Italian Forged Carbon and is 40% lighter than standard nylon highbacks. This provides an extremely direct edge-to-edge response and almost unparalleled precision in your turns. Every movement is immediately translated into control, enabling you to ride confidently at high speed and choose aggressive lines.
Comfort and ease of use have also been refined down to the smallest details. The Phantom Slim ankle straps are 25% lighter than the Exoframe 4.0 straps, without compromising comfort or support. They wrap your boots securely and ensure direct power transfer. The TS 6.0 toe straps keep your boots perfectly in place, even in the most challenging conditions.
In addition, the Source Pro is equipped with Union’s latest ratchet system. This offers a longer lifespan and improved spring return, making entry and adjustments smoother and more reliable than ever. Even in cold and rough conditions, everything continues to operate smoothly.
With its minimalist design, extremely low weight, and uncompromising performance, the Union Source Pro is made for the most demanding riders in the world. This binding is not an upgrade, but a complete evolution in how direct a snowboard binding can feel. For those who want only the best and accept no compromises, the Source Pro is the ultimate choice.
