Campus 彈蓋水壺 600 ml - 冷薄荷

The click-to-close cap is oddly satisfying and it actually stays sealed in my bag, no leaks so far. Light enough to toss in a tote, and the mint color is nicer in person than in the photos.

Filled it with sparkling water and it didn't leak a drop in my bag all day. The cap stays flipped up while I drink so I'm not fighting it every sip, and it clicks shut solidly.

The button flap opens one-handed which is perfect when I'm mid-commute on my bike. It's survived a few drops already and hasn't leaked in my backpack, plus the mint color makes it easy to spot in a crowded gym bag.
