Simple Modern Trek Pivot Tumbler

Yes, the Trek Pivot lid is designed to be leakproof when closed, making it a reliable option for backpacks and lunchboxes. However, like most straw lids, it should be kept in the closed position when not in use to prevent spills.

Yes, the entire assembly, including the lid and silicone boot, is dishwasher safe. We recommend placing the lid on the top rack for the best results.

With a width of 2.8 inches, this tumbler is designed to fit in most standard cup holders. It is a slim profile, but it is always a good idea to double-check the specific dimensions of your car seat or stroller cup holder if you have a non-standard model.

The double-wall vacuum insulation is highly effective at maintaining cold temperatures for several hours. While performance can vary based on the ambient temperature and how often the lid is opened, it is built to keep drinks chilled throughout a standard school day.

Yes, the silicone boot is removable. You can take it off for a deeper clean or if you prefer a sleeker look, though keeping it on provides extra grip and protection against drops.
