Is The Pacto Leak Proof?

No, the SHO Pacto is not leak proof. 

However, our Pacto does come with a closable, splash proof Slider Lid as standard.

Splash proof means that the lid will slow down any major spillages and will stop your drinks from sloshing out of the top when you're on-the-move but you will still see some leaking if this is tipped upside down. Due to this, we do recommend that the Pacto is carried upright when it's in use.
