Sea Grip Chalk

The same clean, ocean-derived chalk as the liquid formula, in the classic powder format climbers already trust.

Sea Grip's magnesium carbonate is drawn from mineral-rich seawater and concentrated through solar evaporation rather than traditional mining — a genuinely different sourcing process, not just marketing language, and one that results in a single-ingredient chalk with nothing else mixed in. No rosin, no silica, no fillers bulking out the bag. Every 275g purchase also removes a pound of at-risk ocean plastic through the brand's Oceanworks™ partnership, so the sustainability angle carries through the whole Sea Grip line, not just the liquid and refill formats.
