Just OK

Not terrible, not great. A little smaller than I would have liked

Great boulder chalk bag

Really like this bag because it’s big enough for both hands to chalk up, has pockets for phone and brush, but isn’t so big that its a pain to take around from route to route in the gym. My only gripe is that I wish there was a design feature for transport, like an obvious handle. Overall though, 98% satisfied!

Great chalk bag

The bag is awesome only thing that I think that can get better is the opening having a magnet to hold it closed when not in use.

Awesome chalk bag.

Works great I've used it many times indoor and outdoor. It's got a nice soft interior and it keeps your chalk really dry. I've spilt water on my bag and it still kept it dry. It has a huge lip that keeps chalk in the bag and off the ground. Overall it has performed great and I'd highly recommend.

Fancy

Owning one of these makes me feel like I can climb 1 to 2 grades higher. this product is a must have when bouldering to avoid spilling chalk when using the small once.

First Ever Chalk Bucket

Wanted a chalk bucket to hold large volumes and to get my hands chalked up nicely. Worked perfectly and has a very nice and simple aesthetic. My only gripe with this chalk bucket is the zip storage. I'm likely also asking too much of it, but I would like it to hold my brush more securely. Similar to my old chalk bag that has an elastic loop for me to slip my brush into and it holds it securely and I'm not worried about losing it.

great chalk bag!!

Loads of volume for chalk, but the two side pockets work great for your wallet and phone 10/10

It is a little bit small, but the flat bottom and roll top are perfect! The zipper pouch is perfect for keys and headphones while the elastic pocket is perfectly phone sized. I just clip on my shoes when I boulder at the gym. The roll top keeps all my chalk inside without the usual spillage. I would definitely recommend as long as you don't need a huge bag.

The bag has a roll top to prevent chalk from going everywhere during transport. It has 2 pockets; one is a zip pocket to hold loose items, the other pocket is a net pocket that can hold an XL sized phone. Visually the chalk bag is appealing with the roll top design of mountaintops. The bag is overall well constructed and holds its shape very well.
