Description

The Rungne Double Boaring Chalk Brush is a premium climbing brush engineered specifically for indoor boulderers and outdoor crag enthusiasts who demand maximum friction on every hold. Designed by professional climbers, this innovative brush features an oversized double-width head packed with thousands of densely packed natural boar's hair bristles. By covering twice the surface area of a standard climbing brush, it makes quick work of clearing caked-on chalk, shoe rubber, and grime from slopers, ledges, and large volume holds—whether you are working projects at your local gym or brushing out sandstone crimps in the Blue Mountains.

Crafted with an ergonomic, heavy-duty handle made from recycled plastic, the Double Boaring Brush provides comfortable, slip-free leverage even when scrubbing overhead or at awkward angles. The stiff, durable natural boar's hair bristles absorb moisture and clean deep into porous rock without damaging or polishing delicate friction surfaces like soft synthetic bristles can.

Complete with an integrated shaft angle designed for efficient power transfer and a sleek, modern aesthetic, the Rungne Double Boaring Brush fits easily into standard chalk bag brush loops and boulder bucket holders, making it an essential tool for serious climbers aiming for peak grip performance.
