Contigo Dark Ice Beverage|Water Bottles, 1 Count (Pack of 1)

I love this tumbler. I bought this to bring my coffee to school and work with me without having to hold it in my hand. I had tried other bottles but even putting them in the side pocket of my bag, they would spill and leak out of the straw hole. This one is absolutely leak proof from my experience. I have even tried holding the bottle completely upside down for a while and it has not leaked at all. I love that there is also a straw option for drinking, as I have not been able to find something leakproof with a straw before this. It has also been able to keep my drink cold all day (I have not tried with a hot drink yet). The only slight inconvenience is cleaning it. The lid has a few parts that come apart for cleaning (I'm sure you can probably scrub it put together and be fine tho) which were a little hard to figure out at first. I looked up a YouTube video (from the Contigo channel) and have now gotten the hang of it and it is not too bad once you're used to it. Definitely recommend!

Great bottle! so far used it mostly for cold water, keeps the water cold as promised. Easy to clean.

Excellent quality! Seals good l. Keep your liquid cold or hot for a good time. Will recommend.

It keeps my ice all day, I love that. But going from auto seal travel mugs to this takes getting used to. If you don't remember spin it closed it makes a HUGE mess if knocked over.

This company always does a great job, but I love that this one has two options. I love that I can choose to have a straw, or I can be strictly sipping coffee mug. There is no leaking and it is amazing!
