A gas mask water pipe, also known as a gas mask bong, combines the functionality of a water pipe with the visual appeal of a gas mask. They are typically made of a combination of glass, silicone, and plastic, with a gas mask attachment that covers the user's face and provides a unique smoking experience. The gas mask attachment is typically made of silicone or rubber and fits over the user's face like a traditional gas mask. The mask is attached to the water pipe via a plastic or metal hose, which allows smoke to be drawn from the pipe and into the mask. The mask typically has a clear window or visor, which enables the user to see the smoke as they inhale it.

Gas mask water pipes are known for their visually striking appearance and unique smoking experience. However, they can also be quite challenging to use, especially for novice smokers, as the mask can make it difficult to see or breathe. They also require much lung power to operate effectively, as the user must draw smoke through the water pipe and into the mask.
