Owala SmoothSip Slider 12oz Insulated Stainless Steel Coffee Tumbler - BPA Free Reusable Travel Mug for Hot & Iced Coffee, Grey/Blue (High Dive) - Perfect for Office, Commuting & Outdoor Activities

I have an owala water bottle that I absolutely love, and decided to buy this for my friend as a Christmas present. She said that this is the best coffee mug she has ever used and even bought herself the smaller version after being gifted the larger size. I also decided to treat myself to one and I can say this is the best travel coffee tumbler/mug I've ever used as well. The cup fits in most car cup holders (even the strange Tesla ones). It is aesthetically pleasing and makes using it fun. It is ergonomic and functions well in terms of retaining heat/cold & minimizing spills. Even the sip quality is enjoyable- I have great control with how much coffee I want to sip and the ease with how I drink my coffee is lovely. Lastly it is easy to clean- you can truly break apart the whole owala so you don't have to go through painstaking measures to get the whole mug cleaned (I'm talking about the weird crevices between the sliding features that I can never get with other travel mugs/tumblers). I'm not sure how else to describe the positive difference the owala makes compared to other travel tumblers- you may just need to try it for yourself!
