Here's what others have to say...

It's chalk...

  • Familiarity: I've put it through the wringer

I basically think all chalk is the same...except for bison. But this sure gets the job done and I'm not gonna lie, the coffee style bag is kinda cool!

Mammut chalk gives you wings

  • Familiarity: I've put it through the wringer

There isn't too much to say about chalk. I have used many brands over the years (Bison, BD, Metolious, Mammut) and honestly they all work relatively the same. This chalk seems to cure sweaty hands so its good enough for me.

Sweat palms no more!

  • Familiarity: I've put it through the wringer

I have extremely sweaty palms, specially when i climb or even think about climbing! i started using this chalk and i haven't had issues! i also started using DMT liquid chalk as a base and then this i can do a multipitch without having to seriously re-chalk!

No sweat if you got sweaty hands

  • Familiarity: I've used it several times

When I climb my hands get extremely sweaty, chalk is chalk however I have found that this chalk keeps my hands dryer than a lot of others that I have used. I also really like how it stays on your hands for awhile, which is nice when trying out hard and long boulder problems.

Great Chalk

I used to suck at climbing, until I got this chalk.

The best chalk

This is a really good chalk. For me now is the only one that I will use. I tried others and just don't like it.

One thing, I order 20 of these, and 1 came with the bag break and "fix" with tape, not a big problem but well, It's just that little detail.

I have the sweaty hands, Mammut Chalk solved the problem. I would venture to say its better than your 1$ brown bag of gym chalk.

Good Chalk

Overall, a good chalk. I mean, all chalks will get the job done, but it's really your personal preference what feels best.

I've used this Mammut chalk and Black Diamond White Gold. To me, the Mammut feels a little more thick or sticky. The Black Diamond feels a little more thin on your hands. It's really hard to give an accurate description about how each feels. The best comparison I can think of is how different face lotions feel. Some are thick, stay on your face longer and some are thinner, absorbed faster. Kinda like that-

You decide which works best for you.

Solid Product

It's very chalky!
As an individual who suffers from sweaty hands while I climb, this clears it right up.

Chalk is chalk and there is really nothing special about it other than it is a necessity when climbing to keep your hands dry so you can grip those tiny crimpers.
