Psychi Powder Climbing Chalk is high-purity loose chalk made from seawater, not mined. Produced from recycled seawater desalination by-products, it sidesteps environmentally damaging mining while giving you the grip, absorption and quality you'd expect from pharmaceutical-grade magnesium carbonate.
The particle size is optimised for climbers: fine enough to absorb sweat and coat your hands evenly, with no fillers, bulking agents or heavy metals. It comes in a biodegradable zip-lock bag in 100g, 200g and 300g sizes. Choose the powder when you want ready-to-use loose chalk for your bag or bucket, indoors or out.
