Union Source Snowboard Binding Black 2027
The Union Source delivers a balanced ride for snowboarders who want dependable performance without the aggressive feel of the Source FC or Source Pro. A more forgiving highback, wider ankle straps, and a nylon baseplate create a setup that's comfortable, supportive, and still keeps the close connection to the snowboard.
This binding features Union's Direct Connect Mounting System for easy setup, lightweight design for reduced fatigue, and reduced baseplate height for better board feel. The Source is perfect for riders looking to progress their skills across all mountain terrain with a binding that won't hold them back.
