The mu stick delivers friction where you need it by blasting fast-moving air from our detachable Turbofan Unit to the brush end of our 8 foot long stick brush. Clean holds on your highball project and detach the Turbofan to cool and dry your hands before each attempt for the best possible conditions each time. The mu stick’s compact, lightweight design allows you to bring the best friction to your project, whether that’s a home wall or remote alpine boulders.
Our v-mount attachment system allows you to snap on accessories to make your mu stick even more useful. Add a boar’s hair sloper brush to get that scary sloper feeling good, an action camera mount to get the best angle on your sends, a tripod for drying or cooling holds, or a stick clip attachment for a day of sport climbing.
We named our flagship product the mu stick because in engineering the Greek letter mu (µ) represents the coefficient of friction. µ means friction. Friction means sending.
Clean the holds.
Dry your hands.
