IceFlowTM 패스트 플로우 뚜껑 텀블러 | 40 OZ

I was skeptical about the lid at first, but it really is leak proof—tossed it in my gym bag sideways and not a drop came out. The 40 oz means I actually finish my water for the day without getting up for refills.

The 40 oz capacity is a serious upgrade—I'm refilling way less than with my old bottle, and the fast flow lid actually pours quickly without splashing. It's been sitting on my desk all day and hasn't leaked a drop, which is exactly what I needed for carrying it around.

I’ve been leaving it in my car during these hot afternoons and the 40 oz size means I’m not stopping for refills every hour. The fast flow lid pours smooth without any splashing, which is exactly what I needed for driving.
