The Union Source is a mid-flex binding built for riders who want a connected, responsive feel without the stiffness of a competition-oriented setup. It suits all-mountain snowboarders and progressing riders who log full days on varied terrain and value comfort as much as control.
Built around the S10 Halo Duraflex CB Baseplate — a two-layer construction combining a Duraflex CB Frame with a Duraflex CB Core — the Source delivers balanced flex and reliable response underfoot. A forgiving highback reduces fatigue on longer runs, while wider ankle straps spread pressure evenly across the foot. The lightweight nylon baseplate keeps swing weight low without sacrificing board feel. Mounting uses Union's Direct Connect system. Available sizes: M, L.
The Source is a strong pick for intermediate to advanced riders who want an honest, all-day binding that doesn't fight them. If you're chasing park laps, groomed runs, and the occasional powder day without swapping gear, this binding handles the range. Riders who found stiffer bindings tiring but want more feedback than a pure beginner setup will find the Source sits right in that sweet spot.
