The Union Source Pro is not just another binding update. It’s a completely new approach to how a binding connects to the board.
The key feature is Union’s new mounting system, using just two screws positioned perpendicular to the board. No traditional disc, less material underfoot, faster adjustment and a much more direct connection between rider and board. The result is a lower-profile base, improved board feel and an incredibly precise response.
Built with Forged Carbon components, the Source Pro sits at the sharp end of Union’s all-mountain range. Fast, powerful and extremely reactive, it’s designed for riders looking for maximum control on hardpack, technical terrain and high-speed freeride lines.
Less hardware. Less interference. More board.
The Union Source Pro is made for riders who want an ultra-responsive all-mountain binding with premium construction, precise power transfer and next-level board feel.
