Climbing here in Saxony is legendary. But the chalk not being allowed… The friction is zero and the sandstone is really harsh to your skin.

So we worked together with Mammut to find a solution to cool the bloodstream so you can finally climb hard without violating local ethics. We found a revolutionary solution Cryo-Grip to cool the bloodstream so you can finally climb hard everywhere. The polish contains endothermic microcrystals that react to adrenaline. Long story short = the more pumped or more scared you are, the cooler your skin is and the better friction you have.

Magnus from Mammut development:

We’re here at Mammut headquarters. I'm the head of R&D. We all love our chalk, but it leaves traces. With the new development, we've been working on it for years, and the objective was clear: Climbers should leave absolutely no trace on the rock. Finally, our core principle of respectful climbing is a reality.

Better start thinking about Cryo-Grip and all those stone towers without allowed chalk would be an even bigger paradise
