Spider Chalk Super Performance Chalk contains lab-made, pure magnesium carbonate and our new Chalk Crystals™ . 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 addition of our ultra-concentrated Chalk Crystals™. Used by professional athletes for bouldering, rock climbing, weightlifting, powerlifting and CrossFit.

Tired of the mini-bags of expensive Climbing Chalk?

Spider Chalk Super Performance Chalk comes in an Extra Large 10oz size in a durable, resealable zip-lock bag.

Choose Chunky or Powder texture. Chunky has chunks of our ultra-dense blocks combined with powder.

We manufacture all of our chalk products in the USA. We do not buy chalk from China and Taiwan and put our label on it! This is pure, laboratory-grade magnesium carbonate.
