Campus フリップキャップ付き水筒 600ml - トロピカルオーシャン

Ditched my old metal bottle for this one because it's so much lighter on walks. The 600 ml size is perfect for the gym and the click-close mechanism feels really secure, even with sparkling water.

The one-button flip lid is the reason I grabbed this for campus, and it’s perfect for sipping between lectures without unscrewing anything. It’s handled my fizzy water all day with zero leaks in my backpack, and the tropical print makes it easy to spot on my desk.

I've had this bottle for two weeks now and the one-hand push-button lid is perfect for mid-lecture sips, plus it handles sparkling water without any hiss when opening. Light enough to clip on my backpack without weighing it down.
