Kubek Transit Flip Top | 20 OZ - Stanley Create

I was skeptical about the leakproof claim, but I tossed this into my tote with a laptop and not a single drop escaped. The slim profile actually fits in my car's cupholder, which is more than I can say for my old thermos. It's become my daily coffee companion.

The flip-top lid seals so tight I’ve tossed it in my tote sideways without a single drip, which is a total win for my chaotic mornings. It’s slim enough that my bag doesn’t bulge, and the 20 oz size is just right for my long drive to work.

Fits perfectly in my car’s cupholder and the slim profile slides right into my work bag without bulging. The flip lid seals tight enough that I can toss it sideways without a drop escaping, which is the whole reason I bought it.
