The water bottle is specially designed not to tilt. This allows you to always keep bottle upright when drinking and to empty the entire 1 liter capacity of the water bottle. Should you find it difficult to drink because your chin touches the bottle, you can push the cap further up. This makes drinking easier. However, it may be that the drinking spout comes back harder.
When the litt is tightly closed, the water bottle shouldn't leak. If it does, please contact Team Cabau and provide a video with the leakage. We will do our best to assist you as soon as possible.
