Simple as it may seem, not all gym chalks are made the same, and they’re certainly not interchangeable. Rogue Gym Chalk utilizes magnesium carbonate—a solid, inorganic mineral that is uniquely insoluble in water. This means the chalk won’t dissolve as you sweat. Instead, moisture is quickly absorbed, your grip is maintained, and the risk of dangerous slipping is greatly reduced.

One box of Rogue Gym Chalk includes (8) 2oz blocks, enough to last for months of daily use. Gym owners can also order 5-packs of chalk—which deliver 40 blocks in one affordable shipment. That’s enough to serve an entire team of athletes through a full season and onward.
