The Arc'teryx C40 Chalk Bag—unlike any other.

Instead of making another basic chalk bag like everyone else, Arc'teryx used Schoeller dynamic softshell fabric to give the C40 a unique look and feel. This small-medium-size Arc'teryx chalk bag is just right for bouldering or sport climbing. The C40 Chalk Bag's tapered top allows you to get a quick dab of chalk when you're cruxing on your project. *Only available for US shipment.

Love this chalk bag. The strap on the bag makes it super convenient and easy to use.

Holds chalk

  • Gender: Male
  • Familiarity: I've used it several times

The construction is impressive, as expected from Arc'teryx, but other than that it is a chalk bag. It holds enough chalk and fits my small hands perfectly, but it will not close with a 'full' chalk ball in it. After some use, with the ball smaller, it closed perfectly and doesnt leak chalk. Additionally, it sits really well on the butt, and the stiff brim really helps when you're nervously throwin your hands into it. If I didnt get it on sale ($25), it wouldnt be worth the money though.

just the right amount of chalk

  • Gender: Female
  • Familiarity: I've put it through the wringer

So if you have larger hands I probably would not recommend this bag. However since I have tiny hands this bag is perfect. It fits my chalk sock and a little bit of loose chalk at the bottom! It closes up neatly and packs away really small after the day is done. The reinforced mouth is nice so you can access the chalk with ease and the strap is easy to adjust.

Arc'teryx chalkbag

The best thing about this bag is the tapered opening lined with nylon which makes entry and exit very smooth. The plastic rim stays open and hasn't deformed much even when thrown in a pack. In a pack it doesn't spill or even "puff" chalk out because it closes up super tight. The material is built to last.

Arc'teryx is notorious for having products that I would never buy at full price (or on sale most of the time) because they are just too expensive for what you get but their chalk bags are an exception to that rule.

Great small bag

  • Familiarity: I've used it once or twice and have initial impressions

I have used this bag once now and love it. If a large bag is a must for your then do not get this bag, I have it filled with loose chalk and it is just big enough for me (medium sized hands). Materials seem durable like most Arcteryx gear. I appreciate the smaller size because it takes up less room on the harness.

love it!

  • Familiarity: I've used it several times

I am a totally in love with this chalk bag. Yes its just a bag that holds chalk. Yes you can find something cheaper. But I put this one on and just had to have it. I love the hard ring around the top edge, keeps the bag open and no fumbling around. The draw string closes so tight no chalk gets out onto your other things. I do have small childlike hands, but I chose this over the smaller size so I could get my entire hand in there with room to spare (I wear size 6 in gloves). The outer fabric is durable and beautiful. If you're looking for a nice bag thats comfortable and clean, get this one. You won't be disappointed.

Swag bag

  • Familiarity: I've put it through the wringer

Hard to say one chalk bag is much better than another, as long as they hold chalk, but I have had zero problems with this one. The outer shell is a nice material, soft and flexible, the inside is soft and fleece lined, the drawstring closes up all the way on mine, no chalk gets out. I have small hands (I wear a size S glove), and they fit fine in the bag, no complaints at all about the size. The citronelle color is nice. If the little stuff makes a difference to you in your gear, it�s worth the extra cost, if not, I wouldn�t bother, a chalk bag holds chalk.

Good Product, Not for Me...

  • Gender: Male
  • Familiarity: I've used it several times

In terms of build quality and functionality of the chalk bag, I'd give it a 5 star. I personally like having the belt, so no need for me to cut it to remove. Honestly though, I don't understand why cutting the end piece off is anything for people to be hesitant about... You could always just feed it right back through the plastic clip piece if you wanted the belt on there again. The hard plastic ring to keep the bag open is really nice, makes getting your hand on some chalk a little less fussy than a limp bag...

As others have, though, my hands are too big to quickly get my hand in there when I'm in a sketchy position. For reference, my hand is 4 inches wide at the last thumb knuckle,7.75 inches long from base of palm to middle fingertip. Also, a large chalk sock will pretty much take up the entire volume of this bag when cinched shut... I am going to give my girlfriend this bag and upgrade myself to the C80.

drawstring broke

Pretty good chalk bag, I've had it for over 2 years now. It works well and does what it needs to but recently the string broke on the bag and chalk went everywhere in my climbing bag. Still for about $30 I'm not going to complain.

too small

this chalk bag seemed to have a solid construction however it was really small it would hardly hold the chalk ball so I got a Petzl Koda instead and that bag is nice and big

Tough to Close

  • Gender: Male
  • Familiarity: I've put it through the wringer

I really like the material of this bag and the size. Colors are bright and the belt works great. The pull cord is a little weak and it is hard to get the bag to close all the way, you really have to crank on it if you don't want chalk all over in your gear bag.

Nice bag for big hands

  • Familiarity: I've put it through the wringer

Love the solid top ring to keep the bag nice and open... and the cinch pulls down nice and tight so I don't have chalk all over the inside of my backpack.

I prefer this bag over my Prana chalk bag because the Dead Bird bag fits my large hands well.

Great Feel!

Okay, I've had this chalk bag for a few months now, and I have really enjoyed it. This chalk bag fits my hands perfectly, but remember that I'm only fourteen years old. It looks nice on the outside, and on the inside it feels really nice. All of the Black Diamond and Organic chalk bags that I've used have a really weird feeling on the inside. On those, it feels like a wool blanket on the inside. But with this one, it has none of that and fells very smooth on the inside of it. The belt is very nice and fits even around my tiny waist. The only complaint that I have is that clipping it to your haul loop with a non-locker is a little awkward, but that doesn't affect me because I don't do that. I really think this is a great purchase if you're going to get serious about climbing like I have.

It's too small for my liking and I have tiny hands. So i turned into my gym bag. It's a nice looking bag though.

Great for chalking up your fingertips, pretty useless if you need chalk anywhere past the second knuckle.

If the belt is cut off, can the bag still...

If the belt is cut off, can the bag still attach nicely to the haul loop?

Responded on

not particularly, see when the webbing is gone all you have is the plastic ring, my best idea is a small biner through the plastic loop then the haul loop, but because of the angle the loop on the bag is at the bag will be turned in a weird way. the webbing runs through the loop parallel to your body whereas a carabiner would be perpendicular, making the bag turn sideways. so id say to just use the belt or be creative to keep that bag facing the right way, theres no shame with modifying some of your gear, just be careful if you want your warranty

Best Answer Responded on

What you could also do, emi, is cinch up the belt loop so that you can clip in a regular biner to your haul loop, and loop through the new belt loop. Then, you could cut the excess nylon from the belt, and melt the frays so that you have a neat platform to play with, the haul loop and the new belt loop.

Not Durable, Doesn't Close all the Way

This bag serves its purpose well. I don't have very large hands, so it does fit me fine.

This bag does not close well. I really have to pull on the draw string in order to prevent chalk from spilling out. After about a month of use, that lead to the grommet that the drawstring goes through breaking off. There is a plastic piece inside of the bag that the drawstring is fed through that came out as well. Now, in order to close it, I have to push this piece back through the hole, and pull on one side of the drawstring to tighten it.

All of the Arc'teryx bags look like they have the same design for the drawstring closure.

I plan on replacing this and going with a different brand bag in the future.
