Pure chalk with a proper crunch. YY Vertical Crunchy Chalk is a crushed, chunky-textured climbing chalk made from 99.7% magnesium carbonate with no fillers and no fragrance, for dry, reliable friction on smooth or greasy holds.

Because the texture is coarse rather than a fine powder, you get that classic crunch between your fingers and can control how much goes on with each dip instead of losing half of it in a cloud. It comes in a resealable 500g pouch, which makes it an easy refill for your chalk bag or the chalk pot at home or at the wall. Choose it if you prefer a chunky loose chalk to a fine powder.

Why you'll love it
