Campus 600ml フリップキャップボトル Little Dutch - Fairy Garden

The clapet lid is such a smart design, my daughter can drink one-handed while the cap stays flipped up instead of smacking her in the nose. It hasn't leaked a drop in her backpack either, and it's light enough that she actually carries it.

I filled it with sparkling water and it didn't leak a drop in my bag, which I wasn't expecting from a kids' bottle. The flip cap stays up while drinking so nothing bonks you in the nose.

The push-button lid is genius — my son can open it one-handed and the cap stays up while he drinks, no more losing the top. It doesn't leak in his backpack either, and I've even put fizzy water in it without any drama.
