Tokyo Powder BLACK vs RX vs V3: The Technical Comparison Guide
When you are looking for the absolute best friction on the rock, generic climbing chalk is rarely enough. Tokyo Powder Industries has changed the game by engineering specialized formulas for different rock types and weather conditions.
At Gripstone, as the official EU representative for Tokyo Powder, we want to help you understand the science behind these products so you can choose the right tool for your next project. Here is the technical breakdown of the three main formulas: BLACK, RX, and V3.
Tokyo Powder BLACK: The Professional Standard
Tokyo Powder BLACK is widely considered the highest-performance all-around climbing chalk on the market. It is designed for elite performance where every bit of friction counts.
The Science of BLACK
The foundation of this formula is nearly 99.9% pure synthesized Magnesium Carbonate. What makes BLACK unique is the addition of specific minerals derived from Japanese Onsen (Hot Springs). These minerals give the chalk a slightly acidic pH level. To learn more about how Tokyo Powder synthesises chalk, check out The Science of Tokyo Powder.
Why it Performs
As you climb, the pH of your skin changes due to sweat, often leading to a "greasy" feeling. The Onsen minerals in the BLACK formula help regulate your skin's pH, keeping it in the optimal high-friction zone. It provides a very thin, silky layer that stays on your skin through long, technical sequences.
Best Use-Cases
We recommend Tokyo Powder BLACK for hard bouldering and sport projects on granite or sandstone. It is also the perfect choice for indoor training where consistency is key.
Tokyo Powder RX: The Friction Booster
Tokyo Powder RX is not just chalk; it is a friction-enhancing specialist. It was specifically developed for the most difficult conditions, such as polished rock or high-intensity efforts.
The Science of RX
Unlike the silky texture of BLACK, RX has a slightly coarser, high-density grain. It is engineered with a specific grain size designed to "bite" into the surface of the rock. It also contains a higher concentration of moisture-binding agents to handle heavy sweat.
Why it Performs
On polished limestone—common in regions like the Moravian Karst or Slovenia—fine chalk can sometimes act as a lubricant. The coarser texture of RX creates a mechanical "grip" between your fingerprints and the rock. If your fingers feel like they are "leaking" moisture during a move, RX is designed to lock that moisture away instantly. RX is our top recommendation for the polished limestone of the Moravian Karst.
Best Use-Cases
RX is the "secret weapon" for polished limestone, glassy holds, and climbers who naturally have very sweaty palms. It is also excellent for plastic gym holds that have lost their texture.
Tokyo Powder V3: The Humidity Specialist
Humidity is the enemy of friction. Tokyo Powder V3 was developed to combat the brutal, damp rainy seasons of Japan, making it the world leader in moisture management.
The Science of V3
V3 uses high-purity magnesium combined with a proprietary moisture-lock agent. This formula is more aggressive than standard chalk at preventing the powder from turning into "paste" when exposed to water or humid air.
Why it Performs
In humid river valleys or Mediterranean crags, moisture in the air can make your chalk feel slimy. V3 remains "crisp" and dry even in 70% to 80% humidity. It ensures that moisture is trapped inside the chalk particles rather than sitting on your skin, allowing you to maintain grip in conditions where other chalks fail.
Best Use-Cases
Choose V3 for hot summer sessions, damp river valley crags, or humid indoor gyms. It is the essential choice for summer climbing in places like the Elbe Valley or coastal crags.
How to Choose Your Formula
To simplify your choice, we suggest looking at your primary climbing environment.
For technical climbing on granite, sandstone, or indoors, Tokyo Powder BLACK is the best all-around choice. If you are climbing on polished limestone or struggle with very sweaty hands, Tokyo Powder RX will give you the extra mechanical friction you need. If you are climbing in hot, humid weather or damp environments, Tokyo Powder V3 is designed to keep you dry.
The Gripstone Layering Method
For the ultimate performance, many of our athletes use a layering technique. They apply a base layer of RX to create texture and absorb initial sweat, then use BLACK or EFFECT during the climb to maintain a smooth, high-friction finish.
