The grain size of this chalk is 400 mesh, a bit lighter/crumblier than some chalk blocks at same volume. These blocks made from the finer powder are better at getting into the grooves of the hand and providing increased grip.
Strengthshop chalk uses a magensium carbonate formula which gives you a reliable and firm grip during lifting. Sweaty palms are a nuisance in the gym, so we designed a chalk that would consistently keep your hands dry thoughout workouts.
