Why your chalk keeps quitting halfway through a session

TL;DR: Most chalk on the market is straight fine or straight chunky, so you're stuck with one texture for the whole session. POUFF blends both, 80% chunky to 20% fine, so you get quick coverage up front and enough texture left in the bag to decide how much chalk you actually want as the session goes on.

The re-chalking problem

You chalk up, hands feel bone dry, and for a second everything's great. Then two moves in, that dryness is gone and you're wiping your palms on your pants again, wondering whether it's your hands or the chalk.

Usually it's the chalk. If you're using a mostly-fine chalk, it feels incredible straight out of the bag, with even coverage and a fast dry finish. The catch is that it's also the first thing to rub off, so you end up re-chalking every attempt whether you need to or not. On a warmup that's just annoying. Mid-crux, it's the last thing you want to be dealing with.

What does "80/20" actually mean?

It's not a different mineral. Every chalk on the market is roughly the same magnesium carbonate. What changes is the texture, and how much of each texture ends up in the bag.

Most chalk leans hard toward one end or the other: straight fine, or straight chunky. Whichever bag you grab, that's the texture you're stuck with for the session. A blended ratio changes that.

The fine 20% is what coats your hands the moment you chalk up: quick, even, dry. The 80% chunky portion isn't there to slowly dissolve on its own timeline. It's there as raw material you control. Rub it between your fingers and you decide how far to break it down, depending on what the moment calls for. Sweating more than usual and want a heavier coat? Work it down further. Don't want a cloud of dust on every hold, or you just like the feel of it more textured in your hand? Leave it chunkier. And when you want to tick a hold so you can find it again on your next go, you need an actual chunk. Fine powder crumbles before it can leave a mark worth anything.

That's the difference a blended ratio makes. Instead of the chalk deciding the texture for you, you decide, whether that comes down to feel, how sweaty you are, or how the chalk sits in your bag between uses.

POUFF runs 20% fine to 80% chunky, weighted toward the part you actually get to use.

Why we use a hard container

The container matters as much as the ratio. POUFF ships in a hard, resealable jar, which gives us more control over how the blend holds its texture from the day it's packed to the last scoop. That control is part of how we keep curating the mix batch to batch, rather than treating the ratio as a one time decision and hoping it holds up.

It's part of why POUFF holds its texture rather than caking together, especially somewhere humid, which describes most gyms on the West Coast.

How can you tell if your chalk is the problem?

A few signs it's the formula and not your grip: you're chalking up every move or two, even on short problems. Your hands go dry immediately and then greasy again within minutes. You've started doubling up on chalk just to get through one attempt, or you can't get a decent chunk when you actually need one to mark a hold.

If a couple of those sound familiar, it's worth trying a different ratio before you blame your technique.

Try it yourself

The easiest way to notice the difference is mid-session, using it alongside whatever chalk you're already carrying. The 35g sample is sized for exactly that: small enough to fit in a chalk bag pocket, with enough chalk for a few real sessions.

FAQ

Is chunky chalk better than fine chalk for climbing? Not on its own. Fine chalk coats quickly but wears off just as fast, while chunky chalk gives you texture you control yourself. Blending the two, at a ratio like 80/20, gets you fast coverage plus the option to work it finer or leave it chunky depending on what you need.

Why do I need chunky chalk instead of just using more fine powder? Fine powder can't hold together long enough to be useful for things like marking a hold. It crumbles before it leaves a real mark. A chunk gives you something solid enough to work with.

How often should I actually need to re-chalk? With a well-balanced formula, every few attempts is normal. If you're re-chalking on nearly every move, that usually points to the chalk rather than your hands.

Does chalk formula matter more indoors or outdoors? It matters in both settings, but it shows up faster outdoors. Humid rock, like granite in the Pacific Northwest, doesn't have a gym's climate control working in your favor.

What's POUFF actually made of? 100% pure magnesium carbonate, blended 80% chunky to 20% fine, made in small batches in Vancouver, BC.

The takeaway

The ratio does more work than most people give it credit for. An 80/20 blend gets your hands dry fast and leaves you enough chunk to decide how much chalk you actually want, whether that's grinding it fine on a sweaty day or keeping a nug ready to tick your next hold.
