Took this through a corn maze for two hours and the 16oz size fit perfectly in my jacket pocket without leaking a drop. The lid seals tight enough that I could toss it in my bag afterward.

Kept my coffee hot for a solid four hours during a chilly morning at the corn maze, which I honestly didn't expect from a 16oz bottle. The lid seals tight enough that it survived rolling around in my tote all day without a single leak.

Took this on a hike through a local farm last weekend and the chai stayed hot the whole time. The 16oz size is just right for one person, and it didn't leak a drop in my bag.
