I picked up this Leakproof 22oz Cruiser Lid to replace the original top on my tumbler, and it does exactly what it promises. The twist-to-lock marker lines up easily and I have had zero leaks tossing it in my bag. Taking it apart for cleaning is simple too, and it goes right in the dishwasher. Just remember it only fits the 22oz Leakproof Cruiser, not other sizes. Note it is Final Sale, so check your model before buying. Solid upgrade overall.
