Campus flaska med klafflock 600 ml - Tropical Ocean

Filled it with sparkling water and it didn't leak a drop in my bag all day, which surprised me honestly. The 600 ml size fits perfectly in my bike's bottle holder too.

The button lid is so handy when I'm carrying my bag and drink in one hand. I've been using it for fizzy drinks and it hasn't leaked once in my backpack. Doesn't retain any taste from my drinks either.

Filled it with sparkling water and the click-shut cap held tight in my bag all day. The button pops it open one-handed, which is handy on my bike.
