Forever Haptics.
100% Plastic-free.
100% Toxic-free.
No Plastic.
More Future.
RSTTR climbing holds are made from SandCore, a unique blend of mineral aggregates and bio-based binder, 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 made from natural materials, based on mineral, inorganic fillers and a binder derived from annual plants. No unnatural materials are added.
Natural Material. Real Performance.
RSTTR holds are engineered to maintain a consistently natural grip throughout their entire lifespan, inspired by real sandstone.
Sandstone feeling
Naturally grippy like real sandstone
Impossible to polish: stays grippy forever
100% fossil-free SandCore
SandCore is made of mineral, fillers free of organic carbon and a bio‑based binder.
Lean Production.
Local Manufacturing.
RSTTR is produced in Switzerland with short supply chains, clean processes, and clear environmental standards.
Manufactured in an ISO 9001 and ISO 14001 certified facility
Local production with a focus on resource efficiency
Reduced transport distances thanks to Central European material sourcing
All our materials are REACH-compliant and not listed as SVHC. No toxic substances are added.
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.
