The Swix Racing Roto Natural Hair is a natural-bristle rotary brush designed for ski preparation. It features stiffer bristles that remove excess wax more efficiently and help clean the structure of the ski base.

When working with hard waxes, use the brush as the second step after scraping and brushing with a steel brush. For softer waxes, it can be used as the first brush immediately after scraping.

To reduce dust particles during brushing, Swix recommends using it with the T15-100 rotor cover.
