Black Diamond Chalk Reserve

Don't you love unpacking your bag after an international flight and discovering your chalk bag has barfed its innards all over the rest of your gear? No? Okay, well the Black Diamond Chalk Reserve might be up your alley. Next time you're headed to France for a combo of some fancy Parisian dinners and Fontainebleau bouldering (or "faire du bloc," as the Bleausards say), slip your chalk bag and refills into the roll-top sealed reserve to keep your finger dust off your berets.

Can be used for more than just Chalk

Keep other stuff in here too? Sandwiches, goodies, etc.

Good idea

Seems like a good idea, protect your chalk and stop it from getting everywhere. Haven't had it long enough or used it enough to say accurately how well it works though.

Great Reserve Pouch

I grew tired of finding chalk everywhere, (including in my underwear and my wife’s car) after I went climbing. The BD Chalk Reserve keeps the excess chalk from spilling everywhere. Love it, must have.

Fantastic Chalk Reserve

This is a great little bag. It’s almost comparable to a marine/boating dry-bag. The roll top seals nicely. The seam at the top is thin enough that you roll just a few times without take too much of the bag’s space but not too thing that you’d have to roll a lot if you only had a small amount a chalk. I actually emptied the last of my chalk into a BD chalk pot before this arrived. That said, I have no doubt it would easily fit a decent volume of chalk. It’s large enough that you could easily fit a full 300g bag in this reserve. Overall I would recommend it. This would even work well for a small tech pouch if you wanted to keep some tech or goodies relative waterproof or at least safe and organized.

The roll up design is effective at keeping chalk from getting everywhere. Getting tossed around with a backpack never caused any spillage. The material is not breathable. Must press all the air out before the roll up of the bag becomes puffy. Overall a satisfactory product that performs as intended

Keeps my climbing back pack clean.

Had issues forever with chalk spilling into my back pack until I purchased this.

I didn’t know I needed it!

I use it everyday I do anything with climbing. From hangboard training to my first multi pitch. The convenience of having it around became a must have essential, second to climbing shoes.

No more chalk dust

I love it No more chalk dust in my climbing bags I used to carry extra chalk in a plastic tub But it takes up so much room This bag fits the bill and is well made
