Sustainable Climbing Chalk

Psych Powder is our high-purity magnesium carbonate climbing chalk, made for indoor and outdoor climbing, bouldering and sweaty training sessions.

It is made by combining magnesium from seawater and CO2, giving you a super pure reliable grip without relying on ecologically damaging mining.

The fine particle texture helps the chalk work into the creases of your hands where other climbing chalk can’t, keeping them dry and improving friction on the wall. Choose chunky chalk if you like crushable lumps, or super-fine chalk if you prefer a smooth, silky feel.

Pure, additive-free and packed in a resealable biodegradable bag.
