Are 40oz. tumblers leak proof?

Not entirely! Most 40oz. tumblers come with lids that have a loose-fitting straw hole and an unsecured seal around the rim. This can lead to spills if the tumbler tips over or isn’t upright in a bag. Over time, exposure to heat or certain cleaning products can warp traditional lids, weakening their seal and causing leaks. Our 40oz. Leak proof lid solves these issues with a secure design and durable materials.

How is this lid leak proof?

The included straw fits securely through the bottom of the lid, leaving no gaps for contents to escape, even if the tumbler tips over. In addition, the straw flips up and down so when the tumbler is not in use, the straw can be flipped down. This seamless design ensures a spill-free experience and peace of mind for on-the-go use.
