AVALEISURE 16oz Collapsible Travel Cup - Big, Foldable Silicone Mug with Leak-Proof Lid for Coffee, Water, Tea - Portable Camping, Hiking Mugs

I have a 12oz collapsible silicon mug (by a different manufacturer) which I use all the time. I was looking for a bit larger collapsible mug and thought I would give this a try. I like the look of the cup and how flat it folds down.However, for me the lid at the mouthpiece leaked (my 12oz mug never leaks) and even with the cover in place this mug feels very hot in your hands. I only drink tea so the water is >200'F maybe a coffee drinker would have better luck since that temperature is usually much lower. I also found the cup difficult to collapse after use - some of the folds got "tangled". I have never had this problem with my other cup.

Great mug. Portable, compact. I take it around in my purse and literally "pop" it out when needed. I've never had a barista give me a hard time about it, and contrary to what other reviewers have said, I had no issues with leaking (just make sure the lid is fully screwed on), the silicon overheating, or the cup being too flimsy. I did a lot of research on collapsible cups and went with this one- wouldn't change it!

I love this cups! I am an extremely bio-friendly person, It’s breaks my heart to have to use plastic every single time I buy a coffee or a drink. But also I don’t like to carry a big purse with me so this is the perfect match. I bring it everywhere I go and use all the time. I got one for my boyfriend and my parents and they love them too! Also great for traveling as I always do.

All in all it holds liquids without burning you. I do not recommend this for coffee or anything flavored or colored. The taste/smell doesn’t go away with washing.Also, make sure you are careful putting the lid on. I almost burned myself because it wasn’t aligned properly and it looked like it was.

This cup is perfect for carrying with you when space is at a premium. I'm using it for hot tea when in hotel rooms and it's been great, easy to clean, easy to pack.

This cup is perfect if you make your own smoothies and put in the freezer to take to work the next day. And also great for hot coffee. Fits perfect in any cup holder. I love this cup and then you can collapsed it down so very easy to store away. Just bought another set.

Received these recently. The body of the cup is one-piece silicone and they expand/collapse as shown. Not much real-world experience with it (hence only 4 stars), but filled it with hot coffee, screwed on the cap, snapped down the drink tab and inverted it--not a drop leaked out. The base seems suitably stable.

Used this as my cup for the week-long stay in the woods for a Burning Man Regional Event. I folded this up and down several dozen times over the week and it kept its shape each time. Marvelous how easily (and small!) it folds up. I was worried about its ability to stay upright when opened/sturdiness, but it did not disappoint! Great product. Easy to clean, held up on a wild week kicking around the woods. Just make sure you pop the tab on the drink hole open before expanding/closing the cup otherwise suction will make that super difficult.
