Campus 600ml フリップキャップボトル - Hot Wheels

Filled it with fizzy water and it didn't leak a drop in my kid's backpack all day. The button pops the cap open one-handed, which is great when he's holding a ball in the other hand.

Been using this for a few weeks now and it survives being tossed in a backpack with my kid's stuff. The button pops the cap open and it stays up while drinking, which is way easier than unscrewing a lid one-handed. Fizzy drinks haven't leaked once, and it goes in the dishwasher without any warping.

The push-button lid is perfect for my son’s school bag—he can flip it open and drink without me worrying about losing a separate cap. It’s super light and hasn’t leaked once in his backpack, and I love that it handles sparkling water without fizzing over.
