The Double-Stack Matrix is an 11" medium-sized glass bong with dual stereo matrix percolators that encompasses all sides of each the water chambers combined with incredible function, this bong comes with better filtration to help enhance your smoking experience. 

In the lowest chamber, the water travels through the matrix percolator for incredible diffusion, before the smoke passes through the upper chamber, where the smoke is diffused by a second matrix percolator as it passes upwards to the angeled-neck tube to the mouthpiece. 

A dedicated splash guard will ensure the water never reaches your mouth during your hit, and the sturdy base keeps the Double-Stack Matrix in a perfect resting position.
