The Rosa is Union's featherweight women's binding, built for freestyle laps and relaxed days roaming the whole mountain. A 4/10 flex makes it easy to press, spin and ride switch while you build confidence, and the low weight means less fatigue by the last run of the afternoon. The CP3 highback and Exoframe 2.0 ankle strap stay light without feeling flimsy, and the Universal Disk V2 mounts to 4x4, 4x2, Channel and 3D insert patterns.
