My coffee was still steaming hot after a two-hour commute with this in my bag, the double-wall really does its job. The secure lid with the sliding mechanism feels sturdy and never leaked a drop, even when I tossed it sideways.

The sliding lid mechanism is so smooth I can pop it open one-handed while driving, and my tea stayed piping hot for the whole morning commute. Honestly, the double-wall keeps things exactly where they should be.

The sliding lid mechanism is surprisingly smooth, and I can flip it open one-handed while driving. My tea stayed properly hot for the whole morning commute, which is exactly what I needed from this cup.
