The Invincipole is an 18mm/14mm joint fitting downstem. Crafted from an aerospace grade aluminum module with a full body hard-anodization, the device comfortably admits any 14mm bowl. Invincipole features the world’s first Telescoping Technology extending from 3 inches – 5 ¾ inches fitting a wide range of commonly distributed bongs. Precision lightning ridges make pole extension easy while the inner O-ring seals the directed air flow. The downstem features a percolation diffuser which houses the final ash defense system, our proprietary stainless-steel screen.
