Campus 彈蓋水壺 600 ml - 冷藍

The clapet cap is genius, I can sip one-handed without the lid flopping back in my face. I've been putting fizzy water in it for two weeks and it hasn't leaked in my bag once. 600 ml is the sweet spot for a morning at lectures.

Took this on a muddy hike and the push-button lid meant I could open it one-handed without touching the spout. It survived being tossed in my bag and nothing leaked, even with fizzy water in it.

The click-to-close flap actually seals tight, I threw it in my backpack with a fizzy drink and nothing leaked. Opening it one-handed with the button is handy when I'm walking between classes.
