We designed the lid before anything else. It is the part you touch most, and the part that fails first on a cheap shaker.

One thumb

The flip-lock opens with one thumb and closes with a click you can hear. No thread to line up, nothing to overtighten.

A seal you can remove

The silicone seal sits in its own groove and lifts out for washing. That is the difference between a lid that stays fresh and one that does not.

The same lid on all five

Rep, Pace, Tempo, Load and Split share one lid. Lose it, break it or just want another color, and any lid fits.
