Disney Summit 水瓶（附吸管蓋）

I was worried the straw lid might leak in my bag, but it’s completely leak-proof when closed, and my water stays icy cold for hours.

The vacuum insulation is no joke—my water stayed ice cold through an entire afternoon at the park. And that straw lid really is leak-proof, even when I tossed it sideways in my bag.

I fill this with ice water before bed and it's still cold the next morning. The straw lid is easy to clean and doesn't leak in my bag.
