The Poncho is designed to be a weather resistant cover, not a 'waterproof' case meaning that it can withstand light rain but must not be submerged in water. It is designed to resist water coming from the front and sides of the phone, however the back is not immune to any liquid contact. It also protects the phone from dust, sweat and mud. As for showers and downpours, you will need to use your best judgement to determine if your device will need further protection to keep it dry. Quad Lock reserves the right to not be held responsible for any damages while using the Poncho.
