Chalk is abrasive and the lining holds onto it. A minute of care after a session keeps the bag working for years.
- Empty it, turn it inside out and brush the seams — that's where chalk packs in
- Spot clean with a damp cloth, mild soap if it needs it
- Air dry completely before storing, never a tumble dryer
- Avoid the washing machine: it degrades the PU coating and mats the fleece lining
- Never rinse chalk down a sink — it sets hard in the trap
Designed by us — two climbers who wanted better kit for their own sessions. We weren't trying to launch a brand. We were tired of chalk through the car, gear spread across three bags, and buckets that fell over every time we set them down. Nothing on the market did the job, so we specified the one we wanted to carry.
The Ascend is made in China by a specialist bag factory, over eight months and three sample rounds. Every change on it came from us using those samples: the buckle became two magnets, the mesh pocket was raised to 8.5 cm, one brush loop became three, the mesh was made all black, and the embroidered X was taken down to 6 cm.
The chalk ball and the climbing brush are packed inside every bag at the factory rather than sold as an add-on. That was non-negotiable for us — you should be able to climb with it the day it lands.
Brush + chalk ball, free with every pre-order
Every bag ships with a boar's hair climbing brush and a refillable chalk ball already packed inside — our thanks for backing the first production run. Included free, nothing to add to your cart.
Every detail, and why it's there
We specified this bag ourselves, argued over it with the factory for eight months, and carried the samples to our own sessions. Here's what's on it and what each part is actually for.
Magnetic roll-top — closes with one hand
Two magnets, one on each side. Roll the top down, let go, and it snaps shut — no buckle to line up, no drawcord to pull with chalked-up fingers. That matters more than it sounds: you close this bag forty times a session, and every one of those is one-handed while the other hand still holds a brush or a phone. The first sample came with a plastic buckle. We paid extra per unit to change it, because a buckle is a two-hand job and two hands are exactly what you do not have at the boulder. Roll it down before the drive home and it seals the chalk in.
Wide mouth, fleece-lined inside
The opening takes both hands at once — flat, side by side, with room to work a chalk ball between them instead of poking at it one-handed. Inside, the whole compartment is lined in fleece: chalk clings to the pile and comes off on your hands in an even coat, rather than pooling in the bottom corner where you cannot reach it. The base is thicker composite nylon with a thin PE sheet sewn in, so the mouth keeps its shape when the bag is half empty instead of folding in on itself the moment you set it down.
Three brush loops, sized differently on purpose
A split elastic band on the flank holds three brushes in slots of 2.5 cm, 2 cm and 2 cm. The wide one takes a fat boar-bristle brush, the two narrow ones take a fine brush and whatever third thing you have grown attached to. One loop would have been cheaper. Three keeps them separated and upright, so you grab the right one without looking — and the elastic bites hard enough that nothing works loose on the walk between problems, which is how most people lose brush number one.
Side mesh pocket and a spot for liquid chalk
The side mesh pocket stands 8.5 cm tall. The first sample came back under 7 cm — deep enough to photograph a bottle in, too shallow to keep one there through a session — so we had it raised before signing off on production. Now a bottle sits upright instead of leaning out, and when you are not carrying one it swallows a brush, a roll of tape or a phone you want within reach. There is a dedicated slot for a liquid chalk bottle too, so it stops migrating to the bottom of the bag under everything else.
Zip pocket, back mesh, and the strap mounts underneath
The zipped pocket on the front body is where your phone, keys and wallet live — walled off from the chalk and padded against the ground when you drop the bag on a mat. It fits a Pro Max. The back panel is black nylon mesh for the things you want without opening anything: spare brush, tape, a gym card. Underneath, the webbing mounts carry both the belt and the shoulder strap, and a bottom drawcord cinches the base — shortened in production so a bottle or a layer lashed under there actually stays put.
Waist belt — bucket mode at the boulder
Clip the belt around your waist and the bag rides on your hip, mouth up, both hands free. That is the mode for actually climbing: turn, dip, go, without taking anything off between attempts and without bending down to a bucket on the mat forty times a night. The belt threads through the webbing on the back panel and adjusts on both sides, so it sits where you want it — over a t-shirt in a hot gym or over a puffy at a winter crag.
Shoulder strap — for the walk in
Swap to the shoulder strap and it carries crossbody like a sling. That is the approach mode: the trail, the walk to the gym, the train at 7pm with a bag that does not announce itself as climbing gear. It mounts to the same webbing as the belt, so switching takes a few seconds and you never carry a strap you do not need. The difference between a nice bag and a bag you actually bring is the twenty minutes before you get there.
Top handle — grab and go
Roll the top down and the handle closes at the crown: one hand, straight up off the mat. That is the third mode — between problems, across the parking lot, into the boot of the car — for when you do not want anything clipped to you and do not want to thread a strap. Same bag, nothing to unclip, nothing to loosen. Three ways to carry, and you will use all three in the same session without ever taking the bag apart.
Early bird price for the first production run, brush and chalk ball included. Ships in 2–3 months — you're charged today and we email you the moment it leaves the warehouse.
Pre-order the AscendLook inside the bag
You can't pick this one up in a shop before you buy it, so here is the next best thing: every compartment, every loop and every measurement, photographed and explained.
27 x 15 x 13 cm. Five litres that become eight.
Wide and low, not tall and tippy. That footprint is the whole design brief: it stands on a crash pad without wobbling, it fits under a bench, and it still swallows a session. Roll the top down for a gym night and it sits at five litres. Unroll it for a full crag day and you get eight — the extra three litres are exactly where a hoodie and a pair of shoes go.
5 L rolled — 8 L unrolled — stands up on its own
Both hands. At the same time.
This is the test every chalk bucket should have to pass, and most fail. Two hands go in flat, side by side, with enough room between them to squeeze a chalk ball properly instead of poking at it with one finger. No narrow cylinder, no fishing around at the bottom, no scraping your knuckles on the rim on the way out.
Wide mouth — two-handed chalk up
Fleece that holds the chalk for you
The whole main compartment is lined in fleece. Chalk clings to the pile instead of sliding straight to the bottom, so when you dip your hands you get an even coat off the walls of the bag, not a fistful of powder off the floor of it. It's also the reason the last twenty grams in there are still usable.
Full fleece-lined main compartment
Two magnets. One hand. No aiming.
One magnet each side, not a single one in the middle. Bring the edges together with chalk all over your fingers and they find each other on their own — no buckle to line up, no drawcord to pinch. That's the mode you use between attempts. When it's time to leave, roll the top down first and it seals the chalk in for the drive home.
Magnets for the session — roll down for transport
Three loops, three widths, on purpose
2.5 cm, 2 cm and 2 cm. The wide one takes a fat boar-bristle brush, the narrow ones take a fine brush and a toothbrush-sized one for the small crimps. They're elastic, so a brush stays where you shoved it instead of rattling out on the walk between problems — which is how most people lose their first brush.
2.5 cm + 2 cm + 2 cm elastic loops
8.5 cm of stretch mesh, and we fought for every one
The first sample came back under 7 cm — deep enough to look like a bottle pocket, too shallow to actually hold one through a session. We had it raised to 8.5 cm before signing off. Now a bottle sits in it without leaning out, and when there is no bottle it takes a brush, a roll of tape or a phone you want to grab fast.
8.5 cm tall — raised from the first sample
Everything has a place, so nothing rolls around
Chalk in the middle. Brushes on the flank, upright and grabbable. Liquid chalk in its own slot so the bottle doesn't end up under everything. Tape, keys and the spare brush in the back mesh. Look down into the bag at the boulder and you can see all of it at once — no digging, no unpacking on the mat.
Main compartment — liquid chalk slot — back mesh
Belt, strap, handle — same bag
Both the belt and the shoulder strap mount to the same webbing on the back panel, so switching takes seconds and you never carry a strap you're not using. Belt on for climbing: the bag rides at your hip, mouth up, both hands free. Strap on for the approach and the commute. And with the top rolled down, the handle closes at the crown for a straight grab off the mat.
3 carry modes — both mount to the same webbing
This is what a full session looks like
Bottle in the mesh, brush on the flank, chalk inside, shoes and a layer under the roll-top, phone and keys zipped away at the front. That's a gym night and a crag day in the same bag, and it's the reason people who carry this pattern stop bringing a second duffel.
One bag — gym floor to trailhead
Folds flat when the session is over
Tip out the chalk and the whole thing collapses. It slides into a suitcase for a climbing trip, lies flat on a shelf at home, and doesn't sit in your hallway like a piece of furniture. Structured when it is full, gone when it's not.
Packs flat — travel friendly
The brush and the chalk ball are already inside
Not an upsell, not a checkbox at checkout. Every bag leaves the factory with a bamboo-handled boar bristle brush and a refillable chalk ball packed in the main compartment. That was the one thing we refused to cut: you should be able to open the box and go climb, without a second order.
Bag + bamboo brush + refillable chalk ballStraight answers
When does it ship, and when am I charged?
You're charged when you place the pre-order. The first production run ships in 2–3 months, and we email you tracking the moment your bag leaves the warehouse. No silence in between — if the date moves, you hear it from us first.
Can I cancel or return it?
Cancel any time before it ships and we refund you in full, no questions. Once it lands you have 30 days to send it back unused for a refund. If it arrives damaged or defective, we cover the return shipping and replace it.
What's in the box?
The Ascend, plus a refillable chalk ball and a boar's hair climbing brush, both packed inside the bag at the factory. Nothing to add to your cart and nothing sold separately.
Is this a waist chalk bag or a chalk bucket?
A bucket, and a gear bag at the same time. It stands open on the mat so you can chalk with both hands, and it carries your brushes, tape and a layer. If you mostly climb ropes and need to chalk mid-route, a small waist bag is the right tool — our guide below says so plainly.
Do you ship outside the US?
Not yet. The first run is US-only with free shipping. Join the list on the homepage and you'll be the first to know when we open other countries.
Not sure a bucket is what you need?
We wrote the guides we wanted when we were choosing. No sales pitch — if a waist bag suits your climbing better, they say so.
