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.
