Spider Chalk - The Only Chalk Made in the USA

Why Innovative Chalk Matters

We're getting geeky about chalk! When we came across Spider Chalk, we were impressed to learn that it's the only chalk made in the USA. Then we started talking to James Hobson: the founder, owner, and living-breathing chalk evangelist and were schooled in how much more there is to know! 

What Sets Spider Chalk Apart: Into the Lab

As the only USA manufacturer of gym and weightlifting chalk, Spider Chalk products last two-times longer than conventional chalk. Why? Because their chalk contains pure lab-grade magnesium carbonate (lab-grade is rarely used). 

As James explained to us, "Typically, chalk is mined from limestone in giant slabs and then refined and separated into calcium carbonate (sidewalk chalk) and magnesium carbonate (gym chalk). Magnesium carbonate has excellent drying ability while calcium carbonate, once wet, feels slimy. Higher grades of magnesium carbonate means higher concentrations of magnesium carbonate and lower concentrations of undesirable elements. That's why we offer the highest-grade and purest magnesium carbonate on the planet."

 Magnesium Carbonate - the good stuff!


Don't Forget about Particle Size! 

But even with the highest grade of purity, there are still other factors to consider when making the world's best chalk for athletes. James went on to explain, "The least well-known, often overlooked, and maybe most important aspect of any high-grade, performance chalk is the particle size." 

"Particle size determines the feel of the chalk, the texture. And the texture affects the performance of the chalk. All powder chalk (and therefore all block chalk) has a certain particle size. Larger particles feel similar to sand or salt on the hand and have a rough texture. Those larger particles, while greatly increasing grip, do not fit into the tiny grooves of the hand and immediately rub off. Constant re-chalking just becomes a part of life. Conversely, smaller particles feel like flour and have a smooth, slippery texture. And although it feels slippery on the fingers, the smaller particle size gets into the grooves of your hand and absorbs moisture, which helps your hand stay extra dry." 

Spider Chalk uses multiple particle sizes to get the superior effects of both small, medium, and large particles. The texture of their powder and block chalk is dry and grippy and fits into every tiny space of your fingers, palm, and forearm. The chalk acts as a super friction-enhancing grip aide! 


Since most companies import their chalk and simply just add their label to the package, they do not have control over the particle size or the purity. But because Spider Chalk wanted to offer athletes the ultimate performance chalk, they took even something as seemingly insignificant as particle size into consideration from the beginning. 

The Real Deal

When you use Spider Chalk you can be assured knowing that every chalk batch is lab-tested for consistency, and all the blocks and powders are produced and packaged in the USA. The best chalk ever created! 

Spider Chalk has proven that innovative chalk matters. Better chalk matters. And people do care about USA made products.
