Kubek Trek

The tapered shape slides right into my car’s cup holder without wobbling, and the lid hasn’t leaked a drop even when I tossed it into my bag sideways. The outside stays completely dry too, so no more wet rings on my desk—definitely my new daily driver.

I’ve been using this tumbler for a week now and the lid really does keep my coffee from leaking in the car. The handle makes it easy to carry while I’m walking the dog, though I wish the insulation kept drinks hot just a bit longer.

The tapered shape fits perfectly in my car’s cupholder, and the handle makes carrying it upstairs a lot easier. My only tiny gripe is that the lid isn’t fully spill-proof if you tip it sideways, but for daily commutes it’s been great.
