브라움 컬렉션 트렉 텀블러

The tapered bottom actually fits my car's cupholder, which my last tumbler never did. Straw lid hasn't leaked once, even tipped over on the passenger seat.

I've been taking this thing everywhere and the straw lid really does keep it from spilling when I toss it in my bag. The handle makes it way easier to carry on walks than my old tumbler.

The leak-resistant straw lid is the real winner here — I tossed it in my tote bag sideways and nothing spilled. The handle makes it easy to carry on walks too.
