Long-Lasting Products for a Long-Lasting Environment.
By combining mineral components with bio-based binders, we create climbing holds that are extremely robust, dimensionally stable, and long-lasting.
Their unpolishable surface not only extends performance but also reduces replacement cycles, a real benefit for gyms, route setters, and the environment.
No Plastic.
More Future.
RSTTR climbing holds are made from SandCore, a unique blend of mineral aggregates and bio-based binders, entirely free from plastics and fossil raw materials. The result is a material that harnesses the strength of natural resources without compromising performance or durability.
SandCore is based on renewable binders and is produced using natural fillers sourced from Central Europe. It’s an alternative that not only feels better but is also better for the planet.
