Designed with Torstein Horgmo, the all-new Union Source Pro TH blends freestyle freedom with pro-level performance. A new highback gives it a more playful, freestyle-focused feel, while cushioned Hybrid 3.0 ankle straps deliver the perfect balance of comfort, control, and response. Built for riders who want precision without restriction.
Direct Connect Mounting System
A disk-free mounting system using just two screws and washers, reducing weight while providing strong, responsive energy transfer from rider to snowboard.
Two-Layer Baseplate Construction
Two-layer baseplate construction pairs an ultralightweight Forged Carbon Core with a Duraflex XC Frame, delivering maximum strength, response, and board feel in the lightest baseplate Union has ever built.
Duraflex XC Halo Baseplate Frame
The Duraflex XC Halo Baseplate Frame is lightest baseplate Union has ever created, while still maintaining the mandatory strength-to-weight ratios needed to pass Union’s strict durability tests. The frame also plays the critical role of connecting the baseplate core, bottom bushing, heelcup, ankle and toe straps together. Made with partially sustainable carbon injected Duraflex XC Nylon.
Forged Carbon Baseplate Core
The Forged Carbon DCS Baseplate Core is stiff, responsive, and ultra-lightweight. Through extensive rounds of R&D the Union Lab was able to reduce the baseplate height by 10% getting you as close to the topsheet as possible. This baseplate layer allows for the fastest possible transfer of energy from the rider to the snowboard that Union has ever achieved. Made possible by Union exclusive Forged Carbon.
Hi-Flex HP EVA Bushing
More durable and more cushioned than traditional thermoformed EVA. Hi-Flex EVA bushings act as an additional layer of dampening and shock absorption between you and your snowboard and never lose shape over time. This reduced volume bushing design allows the rider to be as close to the topsheet as possible.
S18 Source TH
Asymmetrical freeride wrap design delivers targeted support and board response. The integrated 3-stage forward lean adjustment allows riders to fine-tune their stance for maximum control in any terrain.
Hybrid 3.0 Ankle Strap
Lightweight and responsive, the Hybrid 3.0 ankle strap features a hot-press EVA core for cushioning and comfort. Its all-new hinge connector makes getting in and out of the binding effortless.
Dual-Layer UltraGrip Toe Strap
Separating the exterior toe strap frame and interior rubber grip allows the strap to form-fit seamlessly to any boot shape on the market for superior grip and response.
