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!
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.
