Like a block of chunky friction. Goes on smooth and dry but coats easily. Sticks to your hands super well with a little boost.

Incredible feel and texture to this chalk. Nice chunks that break smooth and really coat your hands for multiple boulders or extended routes. Adding to your Black powder really does make the most of it!

I hate this chalk. This chalk makes slipping off of holds impossible. I no longer have the joys of a double dry fire and my back smashing into the mats underneath me because of it. I miss that joy.
I've grown depressed because climbing is no longer a challenge to me because of this chalk. I can't remember the last time my hands had sweat.

I mixed this with Tokyo black and my hands won’t let go of holds. Even with my extra sweaty hands this mixture dries them up and keeps me on the wall.

I know chalk is dry, but this chalk is on another level of dry, Upon first feel it feels like 0% moisture content. Soaks into my sweaty ass hands nice and dries things up to make for a more confident grip. For people with super dry hands, I dunno? Try it once to formulate your own opinion.

My final opinion. Its a nice additive to my giant bag of endo chalk. My thought is if the main chalk is sitting in my bag for a while it gathers moisture from the air and my hands. Adding this moves the moister meter closer to dry.

Love it!

This stuff lasts. Mix it with the Tokyo black and get to work.

You feel like you are literally choking the hold. Use it with boost or Tokyo Black is good too.

The Tokyo powder black has been my preferred chalk for some time. I decided to give the RX a try and.... this is now my favorite climbing chalk forevermore. Friction is great and lasts long. The best of the best for those looking for the top shelf.
