Slide-O-Mix has been one of the most popular handslide lubricant options available for decades, renown for providing fast and resistance-free performance.  Slide-O-Mix Rapid Comfort provides what many players find to be an ideal mixture of the lubricant and silicon from the classic Slide-O-Mix in one neat package.  The most popular handslide lubricant in the Trombone Shop! 

Note: Slide-O-Mix tends to separate when exposed to extremes in temperature; keeping it at 40-75 degrees will help to prevent separation and keep it in ideal condition!
