This mouth cap is compatible with standard mouth HydroFlasks. It has some weight to it and the stainless steel pivots are stiff and feel robust. The seal is excellent, and will not leak water even if the bottle is upside down and completely filled. The cap twists until you are met with a tough resistance that indicates you have fully sealed the cap.
