KUMO is a high-performance chalk, built to perform across climates and conditions. Choose ultra-fine powder for smooth, even coverage, or a chunk-and-powder mix for tactile grip and control. KUMO maintains strong friction while keeping dust low, offering consistency you can trust, session after session. Additive-free and refill-ready.
How to choose (quick guide)
-
Pick Powder if you want the fastest, cleanest re-chalks and ultra-even coverage.
-
Pick Mix if you like tactile grip with fewer full re-chalks during longer burns. (70% fine, 30% chunky)
Weight: 300g
For Tactile Sports like Rock Climbing, Weightlifting, Calisthenics, Gymnastics, Pole Dancing
