Magnesium Dry Stone 7A+ Bouldering and Climbing.

At 7A+, we've tried dozens of climbing chalks for bouldering and lead climbing, until we found the one that truly makes a difference: Dry Stone. Specifically designed for climbers with sweaty hands, this chalk adheres and penetrates the pores to offer long-lasting grip, even in the most demanding conditions.

With 100% pure magnesium carbonate, without additives or aggressive ingredients that could damage the skin but with a totally different style. Only the essentials, in their best version.

Available in chunk and powder format to adapt to your climbing routine.

The powder format, more focused on bouldering or speed, with a very fine and adherent texture to the skin.

The chunk format, focused on sport climbing, with a slightly coarser texture, which makes it looser and provides just what you need. However, it's just as adherent for bouldering.
