Used for the first time and there was a noticeable difference instantly.
This chalk is not only many times grippier than any other chalk I've ever used and lasts far longer.
I found myself (for bouldering) only needing to chalk up once per boulder and if I am being honest, I could probably go longer without re-chalking as I am only doing it out of habit!
I let some friends try and as they we dubious about my praise and they were instantly blown away by the performance!
Outstanding chalk, will only be using this going forward from now on.
Well done Magnus!
