Botol Signature Zaire Wade

The leak-proof lid is the star here — I tossed it in my carry-on sideways and not a single drop escaped. The soft carry handle makes it easy to grip one-handed while rushing through security.

The stainless steel body keeps my drink cold for hours, and that leak-proof lid has survived a few rough tosses in my bag without a drop escaping. The soft carry handle is a nice touch for commuting, though I wish the opening were a bit wider for adding ice cubes easily.
