Campus drikkeflaske med klaffekork 600 ml - Princess Power

The click-to-close cap is oddly satisfying, and I love that the lid stays up while I drink so it doesn't smack my nose. Took it on a bike ride with fizzy water and zero leaks.

I've been tossing this in my bag for a week and it hasn't leaked once, even with fizzy water inside. The button pop-top is handy since I can drink one-handed while the cap stays up out of the way.

I've been using this for my fizzy water and it hasn't leaked once in my backpack. The cap stays flipped up while I drink, so I'm not fighting with it mid-sip. Also survived a few drops onto concrete already.
