Leakproof 40oz Cruiser Lid

I was skeptical about the "leakproof" claim, but after tossing it sideways in my bag for a week, not a single drop has escaped. The twist mechanism clicks into place with a satisfying firmness, and it's now my go-to for travel.

Twist the lid shut and toss it in your bag upside down—not a single drop came out during my whole commute. The align-and-twist mechanism is honestly foolproof, even with one hand while juggling groceries.

Took it on a bumpy bike ride with water sloshing around, and not a single drop ended up in my bag. The twist seal is solid and locks in tight, exactly what I needed for tossing it in a backpack.
