STR | Bone

Built for riders who want a stable and comfortable all-mountain binding with reliable support throughout the day, the Union STR combines a sturdy construction with a forgiving flex, making it equally safe for developing riders as it is for those who have already found their style and want a binding that just works.

The Stage 5 Duraflex baseplate provides a solid foundation with good vibration damping, and the S11 Duraflex highback provides a smooth balance between comfort and control. The Exoframe 3.0 ankle strap fits securely without creating pressure points, while the TS 2.1 toe strap molds around the boot and locks in the foot without restricting movement.

The flex lands at 6 out of 10 – stable enough for speed, soft enough to be compliant when you're filing in techniques or cruising around the mountain. The binding is compatible with the most common systems and makes it easy to find the right setup for your board.
