All about Union STR bindings
All about Union STR bindings
Thanks to Duraflex materials and thermo-injected EVA cushioning, this binding offers reliable performance in cold temperatures and on various terrains.
Union STR Black: the all‑mountain binding that helps you progress
The Union STR Black is, for me as a snowboard specialist, the perfect balance of comfort, flexibility and reliability. With a flex rating around 5 (medium) it gives you enough response to steer with control, while remaining forgiving on landings or rough runs. The Stage 5 Duraflex baseplate and S11 Duraflex highback are designed for cold conditions, so your binding keeps performing consistently when it’s freezing.
The Exoframe 3.0 ankle strap fits snugly without pressure points, and the TS 2.1 toe strap fits any type of snowboard boot for a secure fit. Thanks to the tool‑less strap adjustments you can quickly tweak them on the hill without tools – super handy during cold lift lines.
What really sets this binding apart are the details: the thermo‑formed EVA bushing dampens vibrations and allows your board to flex naturally without bumps or dead spots. The Extruded 3D aluminum heel cup offers optimal heel hold while staying lightweight, supported by durable grade 8.8 hardware built to last for years.
I recommend the STR Black for riders who want to upgrade their snowboard skills: from cruising the groomers to hits in the park and slashes in soft powder. Beginners looking for extra forgiveness are better off with a softer binding, since the STR is a bit stiffer than typical entry models. But those ready for the next step get a versatile, durable binding that keeps performing.
