The Extruded 3D Aluminum Heelcup is designed for optimum heel hold and minimization of drag, Union 3D Extruded Aluminum heelcups are the strongest in the business.
The Duraflex highback is designed and tested by Gigi Rüff, this higback is extremely light and comfortable and ensures a pleasant fixation on any mountain.

COMFORT

Multidensity Bushings sustain their function each season - unlike urethane, rubber or other materials that change color and become brittle over time. 
The bindings are canted for a more natural stance on your board.
Exoframe 2.0 Straps are the evolution of the original ExoFrame, with a new shape and hinging system that allows for easier entry. Extremely responsive.
Hexgrip Straps offer multi-Positional options and thermoplastic anti-slip material keeps you locked in and on point. Each version has differing amounts of material based on weight. 

  • Bushings: Canted Multi-Density Thermoformed EVA
  • Ankle strap: Exoframe 2.0
  • Toestrap: Ts-1.0 Hexgrip

USE

Union bindings are equipped with the strongest steel available on the market - Union’s use of Grade 8.8 represents Union’s commitment of delivering the strongest and most reliable bindings on the market today.

The buckles are made of strong aluminium. Not as light as the magnesium ones, but they will do the job year after year.
