Rosa Womens Snowboard Bindings - Light Blue 2027 FAQ
Why is the Rosa called the lightest women's binding?
At 1.46 kg (pair), the Rosa is built specifically for weight savings without sacrificing durability. It uses S8 Duraflex baseplate, aluminum heelcup, and thermoformed EVA bushing—all tuned for minimal heft while maintaining lifetime warranty protection.
Is the 4/10 flex soft enough for park riding?
Yes. The soft 4/10 flex combined with a 7/10 freestyle performance rating and universal V2 disk make the Rosa perfect for park laps, tricks, and all-mountain play. It rewards forgiveness over stiffness.
Will these bindings work on my Burton board?
Yes. The Rosa includes a Universal V2 Disk compatible with 4x2, 4x4, 3D, and Channel systems, so it mounts on Burton and any modern snowboard without adapters.
What warranty comes with the Rosa?
Union backs the baseplate and heelcup with a lifetime warranty, reflecting confidence in the aluminum heelcup durability and Duraflex nylon construction.
