I was skeptical a steel bottle could keep anything cold through a whole gym session, but this one did—ice cubes were still clinking around after two hours of hiking. The 500 ml size fits perfectly in my backpack’s side pocket, and the pattern hasn’t scratched despite being tossed around.

Coffee stays hot for the full morning commute even when I forget it in the car, and the patterned steel exterior still looks brand new after a month of daily knocks in my bag. The 500 ml size is perfect for a proper refill without being bulky.

I’ve had mine for two weeks and the double-wall steel really does keep my coffee scalding hot through a full morning of meetings. The patterned exterior is also grippier than I expected, which is a nice bonus on my commute.
