Every climber has a style. Every style has a chalk.
Not all climbing chalk is the same. Whether you prefer powder chalk for sport climbing, crushed chalk for bouldering, liquid chalk for the gym, or a chalk bomb for controlled application — 8BPLUS uses 100% pure magnesium carbonate (MgCO₃) with zero fillers in every format. Here's how to choose.
Powder
I'm powder chalk - pure MgCO₃, finely ground, nothing added. The classic climbing chalk for sport climbing, trad, and outdoor rock and favourite for many climbers. Effortless chalking up.
Crushed
I'm a mix of small and large chalk chunks. Fill up your chalk bag, dip in, send it. The crunchy bits keep your grip honest on long pitches. The go-to crushed chalk for climbing outdoors, bouldering, sport, or trad.
Liquid
Great gym chalk or to use as a base layer. Squeeze, rub, send. I dry in seconds and leave a base coat that lasts pitches. Indoor climbing gyms love me. No dust cloud, no mess, no dirty looks from the setter.
Chalk bomb
I'm a refillable, big sized chalk ball. Give me a squeeze and only the right amount comes through my pores. Tidy and efficient. The chalk bomb is for climbing sessions where controlled application matters - bouldering and in the climbing gym.
The spec spectrum
WHY YOU WILL LOVE IT
This isn’t just any climbing chalk, it clings, like seriously clings! Delivering solid high friction as you would expect from a premium climbing chalk. Why is that so? Because we’ve spent years testing, refining, and perfecting our magnesium carbonate formula to meet the tough demands of rock climbing and gym chalk use. (And yes, our mischievous little chalk bag critters played their part, making sure we got the mix just right!)
Clingy but skin friendly! We always knew we had to remove impurities and unnatural fillers (and other chemicals) to create a pure magnesium carbonate that’s gentle on your skin and leaves no harmful traces in the environment.
Plus, our chalk bag monsters insisted that clean chalk means cleaner climbs.. and who are we to argue?
Once our chalk formula was perfected, we turned our attention to other details that matter: the production process, timing, and packaging. We can now ensure that each batch of our climbing chalk is processed and packed under optimal conditions, so it stays fresh and effective right up to the moment you open the pack.
The result? A reliable grip for confident climbs.
8BPLUS CHALK FAQ – Because Even Monsters Have Questions
What is climbing chalk made of?
Climbing chalk is made of magnesium carbonate (MgCO₃), a natural mineral, which absorbs sweat and improves grip. Some formulas add drying agents, we don't. 100% pure without fillers or additional chemicals.
What's the difference between powder and crushed climbing chalk?
Powder chalk is finely ground for even coverage and smooth application - great for gym training. Crushed chalk has a chunkier texture for fast, grab-and-go grip - popular outdoors and for bouldering.
Can I use liquid chalk at indoor gyms?
Yes - liquid chalk is the go-to choice for gyms that restrict loose chalk. It dries fast, leaves no mess, and provides a solid base layer you can top up with powder.
Is 8BPLUS chalk eco-friendly?
Yes - 100% pure MgCO₃, no fillers, no synthetic additives, and fully recyclable packaging.
How much chalk do I need?
For regular gym training, a 100g bag lasts most climbers 4–6 weeks. For frequent outdoor sessions, the 250g is better value. The chalk bomb is ideal if you want zero mess.
