Siurana is one of the most demanding climbing sectors in Catalonia — limestone walls where every edge counts. That's where our chalk comes from: a very fine grain, made for fast absorption in moments that leave no room for error.
250g bag, in a Kraft paper DoyPack with a zip-style closure. 100% magnesium carbonate, approved for sports use and compliant with European Union regulations.
"Siurana Outdoors Chalk feels amazing on my fingers, and I love the packaging design and the way it closes. It keeps the chalk contained and prevents it from spreading all over my backpack. Definitely one to try!"
