Thanks to its compact mass, the Transa bouldering brush is ideal for always having with you in your chalk bag when bouldering and climbing. No more excuses about greasy holds, ledges and holes. The Transa bouldering brush is manufactured entirely in Switzerland by the Blinden-Fürsorge-Verein Innerschweiz (BFVI). The handle cleaning brush is therefore also a clever little helper for climbing enthusiasts and supports production in Switzerland. A brush for all occasions.
