SYOS Mouthpiece Cap

A mouthpiece cap that works with every ligature sounds obvious, but most caps don't actually do it. They're designed around a specific ligature position, which means switching setups often means hunting for a different cap or forcing a poor fit. The SYOS cap solves that with a simple, open design that slips over the mouthpiece regardless of what ligature is underneath.

It protects the reed and the tip rail when the horn is down between tunes or in the case — which is exactly when most mouthpiece damage happens. No fuss, no adjustments, no incompatibility. Put it on and trust it.

Our favorite everyday cap, and one of the easiest recommendations we make.
