11" Double Matrix Perc Bong with 80mm Wide Body | Croia Glass

The Croia Glass 11" Double Matrix Perc Bong packs two full stages of filtration into a wide 80mm body. Smoke enters through a side-mounted inlet and passes into the lower chamber, where a large matrix percolator splits it into fine bubbles, then rises into a second stacked chamber with its own matrix perc for another pass. That double diffusion cools and smooths each hit far beyond a single-chamber bong. The clear borosilicate glass shows both percs at work, and a bent neck with a black glass rim gives it a clean scientific look while keeping your face out of the way.

The 80mm width gives the percs room to work without making the bong unusually tall, so at 11 inches it stays easy to handle. A removable glass bowl is included. Add water to the lower chamber, then enough to the upper chamber to cover its matrix openings, and take a test pull to adjust each level. The trade-off with two matrix percs is a bit more drag and more cleaning, since residue can build up in the grids, so give both chambers a regular shake with isopropyl alcohol and salt.

If you want serious filtration in a bong that does not tower over your table, this double matrix is a strong pick. The wide body and stacked percs deliver smooth hits every time.
