Trango REAL Chalk is magnesium carbonate refined directly from seawater rather than extracted from mined mineral deposits. The process yields a high-purity chalk with a finer, more consistent particle size than most mined alternatives — which translates to more even coverage on the hand and better moisture absorption during a session.

Seawater-derived magnesium carbonate offers two practical advantages over mined chalk. First, the refining process removes the trace impurities common in mined chalk that can leave a gritty residue on holds or reduce friction over time. Second, sourcing from seawater reduces the environmental footprint associated with open-pit mining of magnesite deposits, making REAL Chalk a more sustainable choice without any performance trade-off.

The result is a chalk built specifically for climbing performance: consistent in texture, clean on holds, and produced with a lower impact on the environments climbers depend on.
