Disney/Pixar Cold Cup XL

The spill-proof centerline cap actually lives up to the name — I tossed this in my tote on its side and not a drop leaked. The handle makes it way easier to carry on walks too.

The 30oz size is perfect for a long day out, and the handle actually feels comfortable to carry instead of digging into my fingers. I tipped it sideways in my bag and the centerline cap didn't leak a drop.

Filled it with iced coffee and tossed it in my bag sideways on the train, and the centerline cap didn't leak a single drop. The 30oz size gets me through a whole afternoon without refilling.
