THE SOURCE PRO
Bindings are scheduled to arrive in November 2025
Engineered for precision on the mountain
The Union Source Pro delivers a balanced ride for snowboarders who seek performance without the extreme feeling of the Source FC. With a slightly less aggressive highback and wider ankle straps, it offers exceptional comfort and control while maintaining the closest connection possible between the rider and snowboard.
