Magnesium Block 75g

Sierra 56g Chalk Block is a compact magnesium block designed to prepare your hands with a solid, simple, and easy-to-control texture before each climb.

You can use it whole, break it with your hands, or crumble it gradually inside your chalk bag depending on the feel you're looking for.

Its 75g format is practical to carry in your backpack, fill your chalk bag before training, or always have on hand for rock climbing and bouldering gyms.

Sierra's Chalk Block allows you to adjust the texture of the chalk as you prefer: finer, coarser, or directly from the block.

You decide how you want your grip to feel.
