Copo The Quencher ProTour Flip Straw Tumbler | 14 OZ

The flip straw lid is the best part—it actually seals shut, so I can toss it in my work bag without a drop leaking. The 14oz size is perfect for my morning coffee, and the handle makes it easy to grab one-handed while rushing out the door.

The flip straw mechanism is genuinely leakproof—I tossed it in my work bag with coffee and not a drop escaped. The 14oz size is perfect for shorter outings and the handle makes it easy to carry with two other things in hand.

Fits perfectly in my car's cupholder, which was the whole reason I grabbed the 14oz size. The handle makes it easy to carry around the office, and the lid clicks shut securely enough that I don't worry about it in my bag.
