Campus flaska med klafflock 600 ml - Wild Horse

I've been tossing this 600 ml bottle in my bag for a few weeks and it hasn't leaked once, even with fizzy water in it. The flip cap stays up while I drink so I'm not fighting with it one-handed.

I've been tossing this in my bag for a couple weeks and it hasn't leaked once, even with fizzy water in it. The button pop-open is handy when I'm biking and only have one hand free.

The flip-top lid stays open on its own, so I can actually drink one-handed while holding my toddler. It survived a full drop onto concrete and hasn't leaked once in my bag. Fits fizzy water fine too, which most bottles this size don't.
