Spider Chalk Super Performance Powder Chalk

Spider Chalk Super Performance Chalk contains lab-made, pure magnesium carbonate. We created lab-grade powder chalk and you can feel a difference immediately when compared to other climbing chalks. Super Performance Chalk lasts longer and remains dry even during sweaty workouts thanks to the ultra-refined nature of our climbing chalk. Used by professional athletes for bouldering, rock climbing, weightlifting, powerlifting and CrossFit. Tired of the mini-bags of expensive Climbing Chalk?
