Campus vandflaske flip-up 500 ml - Cool blue

Brought this to the park last week and the 500 ml capacity was just right for a few hours outside. The flip-up lid clicks shut securely enough that I'm not worried about it leaking in my bag, which was a nice surprise.

The see-through design is great for keeping track of my water intake during classes. The flip-up mouthpiece makes one-handed drinking really easy between lectures.

I was skeptical about the 500 ml size for school, but it's actually perfect—just enough to keep me hydrated between classes. The transparent bottle makes it easy to track my intake, and the cool blue color looks great in my backpack.
