At FrictionLabs, we deliver The New Standard in Chalk for athletes. Designed to help you consistently perform at your limit, this is not the same old generic chalk ball from China that you?re used to. Athletes demand a lot from themselves and they expect their gear to live up to that standard. We responsibly refine our athletic chalk in Denver, Colorado, wiping out fillers and artificial drying agents like Silica to deliver better performance. Our chalk was designed for the extreme demands of rock climbers and has since become the choice product of National Champions and beginners in any sport that demands confident grip. #chalkmatters, and our goal is to help athletes finally find a chalk they can rely on to keep their hands drier and healthier, longer. QUALITY - Generic chalk just doesn?t get the job done. It?s full of junk from foreign factories with poor quality control. FrictionLabs delivers The New Standard in Chalk, and thankfully more and more athletes of all experience levels are making the change every day. Featured in Popular Mechanics, The Wall Street Journal, Men?s Fitness, Rock & Ice Magazine, and Climbing Magazine. PERFORMANCE - Like a car that gets better MPGs, our high purity Magnesium Carbonate makes a single application go further, giving you the extra edge to focus on the task at hand with less waste. Stop running through bulk chalk?watch a little go a long way. CONFIDENCE - FrictionLabs is the only chalk trusted and endorsed by national champions in multiple sports. 10-Time Champion Alex Puccio, 9-Time Champion Daniel Woods, and 3-Time CrossFit Games Masters Champion Scott Olson are just a few of the 100+ Pros who love and use FrictionLabs chalk.
