Friction Labs Gym Chalk – Magic Ball, PRO Ball (Chalk Bag Sock) | Non-Toxic Climbing Chalk for Bouldering, Gymnastics & More

Friction Labs is redefining what athletes expect from chalk. Developed for the demands of elite climbers, weightlifters, gymnasts, and CrossFit athletes, our high-purity magnesium carbonate offers superior moisture absorption, a cleaner feel, and reliable performance without the use of fillers, drying agents, or silica. Proudly made in Denver, Colorado, our chalk is safe for all skin types and trusted by professionals who know that consistent grip equals consistent results. The Friction Labs Chalk Disc is a smarter, cleaner chalk refill designed specifically for use with the Magic and Magic Pro Chalk Balls. This solid disc format eliminates the mess of loose powder and the hassle of crumbling chalk blocks. Simply drop a disc into your chalk sock or reusable chalk ball shell—press, twist, fold, and smash to your desired consistency. The disc breaks down smoothly inside the sock, delivering a controlled chalk release that keeps your grip dialed in without over-applying. With a precision-engineered circular shape, the Chalk Disc minimizes dust while offering targeted coverage for climbing holds, barbells, rings, or any grip-based activity. Each tube includes five individual 0.85 oz discs (totaling 4.25 oz), making it ideal for regular use and easy to stash in a gym bag or travel kit without the risk of leaks or spills. Whether you’re crushing reps or pulling through cruxes, the Friction Labs Chalk Disc is your cleanest, most efficient chalk solution—designed to refill your Magic Chalk system and help you perform at your best, every session.
