This chalk bag performed well in all of our tests. First of all, it has a very large chalk depositary area. Secondly, the double drawstring closure means that no extra chalk will escape when you don’t want it to. The handle makes it easy to carry around, too.

What really helps this stand out is its extra features. There are four brush holder attachments, which is pretty astonishing.

3. Black Diamond – Mondo Chalk Pot

Essential Info

  • Closure: Magnetic, Clip
  • Pockets: 2 Zip
  • Extras: Brush Holders
  • Weight: 177g

Our Verdict

Black Diamond have really pulled out all the stops for this bouldering chalk bag. The magnetic closure system is wonderfully designed and means you will never spill your chalk. Even so, this means that whenever you remove your hands from the bucket, it automatically closes. This can get frustrating, as you have to open it every time you chalk up.
Nevertheless, there are other features that improve the bag’s functionality. The two zip pockets are very spacious and scored the best for storage in all of our tests. There are also two brush holders for your pleasure. Overall, it is a decent chalk bag and you can really get some good use out of it.

4. Moon Climbing – Deluxe Bouldering Chalk Bucket

Essential Info

  • Closure: Drawstring
  • Pockets: 1 Zip
  • Extras: Brush Holders, Handle
  • Weight: 204g

Our Verdict

The second Moon Climbing bag in our top five is their Deluxe version. It did not perform better than the original, however. It has a drawstring closure system, which whilst good in theory, it does allow some chalk to escape when you are transporting it.
The zip pocket is big enough to store whatever you need and there are also some stash pockets too, which is a nice touch. The best thing we found about this chalk bag was the handle. It really made it easy to carry between problems. It looks nice too, which is a bonus, but there are better bags out there.

What Makes Bouldering Chalk Bags Unique?

Simply put, they are easier to access and hold larger amounts of chalk. Unlike climbing, bouldering routes are relatively short. This means that you don’t need to strap a chalk bag to your waist as you go up the wall. Therefore, bouldering chalk bags have been developed and are sometimes be referred to as chalk buckets.

This is because they look like a bucket or a big pot. Another advantage of having a chalk bucket is that you can get both of your hands in at the same time. You can quickly chalk up and get back on the wall. Of course, you can still use your normal climbing one too, it is just these are more convenient!

How to Choose Bouldering Chalk Bags

Most bouldering chalk bags are pretty similar in terms of design and price range. The things you need to watch out for are closure systems, pockets, size of the bag, and its base. If all these components work well, you have found a solid functioning bag. Let’s have a look in more detail below:

Size and Stability

It is important that your bouldering chalk bag is big enough so you can easily put both hands in at the same time. This allows you to chalk up quickly and efficiently without any wastage. Furthermore, the base should be strong and stable so that it will never fall over.


This is a point of preference. There are drawstring, magnetics, hook-and-loops, clips, roll-top, velcro, and zipper. The major factor here is that you want all chalk to stay inside the bag when you are moving it around, especially when it is in your backpack. Ease of access is also something that should factor into your decision, as you don’t want to be annoyed by your bag.


Having pockets on your bag can really make a difference. There are a number of things you might want to store, such as phone, wallet, tape – or whatever else you think is essential to bring to the wall! The bag should have enough space for whatever you need and the pockets should close properly so nothing falls out.

The Extra Stuff

We are talking about brush holders or handles here. The more brush holders you have the better. Even so, two should be enough to get you through. If the bag has a handle to carry it around it will also make your life easier. At the end of the day, you can’t expect much more from a bouldering chalk bag, but functionality is key.

Now we have come to the end of this review of the best bouldering chalk bags we are sure you have found the one for you. As we have said, many are very similar and at the end of the day, they all do the same job.
