Portable Collapsible Insulated Tumbler - 16 oz

This is a quality collapsible mug. It comes with a good cover and a flexible straw. Although I’m not sure how useful the straw is. I would definitely recommend it if this is what you are in the market for.

Easy to clean, packs nicely into my lunchbox or luggage.

When we walk to dinner and need a couple of roadies but don't want to schlep cups, this is perfect for hot or cold and they are easy to collapse and carry home.

Used this on a trip! Best trip cup ever! Keeps coffee warm for a long time!

Easy to clean, easy to use. My only inconvenient is that you need to clean it pretty well before putting it away, and well in a flight it's a bit difficult to do that. But highly recommended due the space you save to bring your own cup wherever and whenever.
