The Friction Labs® Chalk Disc is a revolutionary transformation of the classic chalk block. Its round form and dependability offer a concentration of application with minimal dust, allowing athletes to boost their grasp in climbing, gymnastics, weightlifting, and beyond-activities that necessitate sure hands. Some people say, "chalk is chalk." Not true. A team of world-class geologists and chemists recently conducted independent tests on 5 of the most common chalks for rock climbing. The results were clear: FrictionLabs chalk is the purest chalk and the best out there. “Chalk C, FrictionLabs, yields the highest Magnesium detection. Chalk C, FrictionLabs, also yields much lower counts for the other elements, hence is the most chemically pure.” - Wesley Ingram Ph. D. Geology and Geochemistry Consultant What is rock climbing chalk? Chalk is mined as Dolomite, a mixture of Magnesium Carbonate, Calcium Carbonate, and numerous other compounds. Magnesium Carbonate When exposed to moisture, Magnesium Carbonate traps water molecules on the inside of its crystalline structure, leaving the surface dry. Calcium Carbonate Calcium Carbonate attaches water to the outside of its structure, causing the surface to feel moist and slimy. Not a good characteristic for grip. So, more Magnesium Carbonate = Drier Hands = Better Performance All climbing chalks market themselves as Magnesium Carbonate, because that's what dries moisture the best. They mislead you into thinking it's only Magnesium Carbonate when the truth is that they all have significant amounts of Calcium Carbonate and other fillers. Calcium Carbonate - the same stuff as chalkboard chalk - just gets slimy when mixed with moisture. When you sweat, keeping your hands dry depends on having chalk that has high amounts of Magnesium Carbonate and low amounts of Calcium Carbonate. Friction Labs had an independent lab test their chalk against the most popular options to see what they're made of. They concluded that, gram for gram, Friction Labs contained over 50% more Magnesium Carbonate than their closest competitor. Friction Labs use a proprietary process to create high-performance chalk with an extremely high Mg: Ca ratio. Because climbers have different texture preferences, FL make their chalk into 3 distinct blends: Bam Bam (Super Chunky), Gorilla Grip (Chunky) and Unicorn Dust (Fine). Eco-friendly Packaging After 4+ years of research and testing, FrictionLabs has upgraded to what they believe best option in sustainable packaging. Now made from 100% recyclable box which has been made using wind energy - clean, non-polluting electricity that does not produce greenhouse gases. Their packaging is manufactured in a zero-waste facility - a vacuum scrap removal system removes all leftover material and sends it directly to the recycling centre. The graphics are printed with soy and vegetable-based inks - derived from renewable soy, linseed, and corn with no petroleum-based ink. The internal chalk bag is also made from 100% recyclable film plastic that will soon be the only domestic, certified 100% recycled clear LDPE film on the market. All this means that the packaging can be recycled at home with ease and should never find itself going to landfill! In Conclusion, If you want dry hands for longer and maximum grip, you want FrictionLabs chalk. Specification Drying Agent: No Manufacturer: FrictionLabs Made in the USA No additives Dairy free Gluten free 100% vegan Each tube contains 4.25oz of chalk in the form of 5 x 0.85oz individual discs.
