The Jaxx USA "The Wolf" Diffuser Bong is an all American made glass piece, designed to offer you the smoothest hits you can imagine.
 
Featuring two separate chambers rammed with percolators, this thing is sure to give you massive, cool and tasty rips. The first lower chamber features a barrel percolator attached horizontally onto the stemless system, so the smoke is cooled and filtered straight from the source. It is then pulled up through the bong to the second chamber/percolator where it is filtered through a percolator that looks like a complex array of cogs. The bong tapers towards the top, reducing the airflow and increasing the negative pressure inside the bong. This helps to make the bong easier to clear, and means the smoke doesn't stay in the chamber too long, getting stale.
