How long does it keep drinks cold?

The double-wall insulation keeps cold beverages cold for up to 24 hours and hot drinks hot for up to 12 hours, depending on ambient temperature and how often you open the lid.

Is it really leak-proof?

Yes, the twist-on lid creates a tight seal when properly secured. The flip straw won't leak even when the tumbler is sideways in a bag, as long as the lid is fully closed.

Can you wash it in the dishwasher?

The tumbler itself is dishwasher safe (top rack recommended), but the lid and straw should be hand-washed to preserve their seals and extend their lifespan.
